- Which of the following would best be solved using completing the square?
A. 22 – 2 – 20 = 0
B. 22 = 36
C. 2x2 + 15x = 6
D. 203 – 3c2 + 45 – 12 = 0
Answer:
C
Step-by-step explanation:
You can only complete the square with quadratic equations (equations leading with x^2)
C is the only answer choice that leads with x^2
Answer:
A
Step-by-step explanation:
Because you would do 22 _2 _20 and your answer will be zero .

- Meagan puts three flowering plants in a garden bed. Plant 1 and Plant 2 are 6 inches apart Plant 2 and Plant 3 are 10 inches apart Plant 1 and Plant 3 are 13 inches apart Did Meagan place the plants in a right triangle shape? Why or why notp?
Answer:
No
Step-by-step explanation:
They can't be in a straight line because 6+10 (the distance between plants 1 and 2 and plants 2 and 3) is more than 13 which is the distance from plant 1 to plant 3. This means plant 3 can't be in line with 1 and 2 which will give a triangular shape. If we check Pythagorean theorem we get 6^2 + 10^2 = 13^2 ( the longest side has to be the hypotenuse) . Since this isn't a true statement it can't be a right triangle.

Pythagorean theorem. Show your work!
Please help in really stuck!!
Answer:
[tex]\sqrt{29[/tex]
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2 = c^2. "a" and "b" represent the side lengths QR and PR, while "c" represents the hypotenuse PQ.
Let's plug in these values:
2^2 + 5^2 = c^2
4 + 25 = c^2
29 = c^2
sqrt 29 = c
Therefore "c" is the square root of 29.
Answer:
My answers is basically 29^2 or [tex]\sqrt{29}[/tex]

A fruit punch is made with 32 ounces of ginger ale for every 12 ounces of frozen orange juice
concentrate. How much ginger ale should you use for 30 ounces of orange juice concentrate?
Answer:
80
Step-by-step explanation:
if you make a ratio table
32ginger ale = 12orange juice
now we now 6x5=20 so we can divide 12 by 2 which would give us 6 and the same with 32 which would give us 16 now you have
16ginger ale = 6 orange juice
and we need 30 orange juice so 6x5= 30 and we multiply 16 by 5 too so 16x5=80 t
therefore
80 ginger ale = 30 orange juice

Answer:
61.3 to infinty
Step-by-step explanation:
1. Multiple: 7(8) = 56
2. Multiple: 2(4) = 8
3. Divide: the result of step 2: 3 = 8 : 3 = 2.6666666666667 = 8/43
4. Multiple: the result of step 3: 4 = 8/3
* 4 = 8 · 4/
3 · 1
= 32/
3
5. Subtract: the result of step 1 - the result of step 4 = 56 - 32/3
= 56/1
- 32/3
= 56 · 3/1 · 3
- 32/3
= 168/3
- 32/3
= 168 - 32/3
= 136/3
6. Multiple: 2(8) = 16
7. Add: the result of step 5 + the result of step 6 = 136/3
+ 16 = 136/3
+ 16/1
= 136/3
+ 16 · 3/ 1 · 3
= 136/3
+ 48/3
= 136 + 48/3
= 184/3

Given a normal distribution with a mean of 28 and a standard deviation of 2.5, what percentage of the data should be between 25.5 and 30.5?
Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:
28 - 2.5 = 25.5.28 + 2.5 = 30.5.Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.

The functions f(x) = x2 – 2 and g(x) = –x2 + 5 are shown on the graph.Explain how to modify the graphs of f(x) and g(x) to graph the solution set to the following system of inequalities. How can the solution set be identified? y > x2 – 2 y ≥ –x2 + 5
Two rigid transformations must be applied:
Vertical translation 7 units in the +y direction.Reflection around the line y = 5.The solution set can be identified by the fact that domain of quadratic functions is the real domain.
How to use rigid transformations
In the field of the Euclidean geometry rigid transformations are transformations applied on geometric loci such that Euclidean distances within the latter are conserved and herein we must determine what rigid transformations we should apply on f(x) to obtain g(x).
After a careful examination, we conclude that following two rigid transformations must be applied:
Vertical translation 7 units in the +y direction.Reflection around the line y = 5.The solution set represents the set of x-values such that the function exists. As both functions are quadratic equations, then their solutions are described the entire real domain.

I'll write in the format (x;y) where x is the salad dressings amount, and y is the amount of servings.
We can see the line goes through the points (1;2) , (2;4) , (3;6) ...
So, the amount of servings are doubled the amount of salad dressings she need to use. (1 cup every 2 servings, 2 cups every 4 servings, etc.)
-> Leslle used half a cup of salad dressing for every serving of salad (B)
Answer:
B.
Step-by-step explanation:
Remember the first value is called the x-coordinate and the second value is the y-coordinate.
Find the first point the line crosses over.
So let's take the point (2,1).
As you can see that for every 2 servings Leslie uses 1 salad dressing cup,
2 to 1
Now look at the answers,
So you can are ready mark off A since it is not true,
You can mark off C since the line does not cross over points (1,4),
You can mark off D since the line does not cross over points (1,2),
That leaves you with B,
To check if it is true you need to find how much salad dressing cups are in one serving,
To do that you need to divide by 2 on both sides,
2÷2=1
1÷2=[tex]\frac{1}{2}[/tex]
your new rate is 1 to [tex]\frac{1}{2}[/tex]
So B is your answer.

Answer:
257mm^2
Step-by-step explanation:
18*(3+15)/2 = 162
4*(15+5) =80
3+5 = 15
total = 257 mm^2
Answer:
Step-by-step explanation:
Area of composite figure:
Shape I:
Shape I is an triangle
base= 3 + 15 + 5 = 23 mm
height = 18 mm
[tex]\boxed{\text{Area of traingle = $\dfrac{1}{2}base*height$}}[/tex]
[tex]= \dfrac{1}{2}*18*23\\\\= 9*23\\\\= 207 \ mm^{2}[/tex]
Shape 2:
Shape 2 is an rectangle.
length = 15 + 5 = 20 mm
width = 4 mm
[tex]\boxed{\text{Area of rectangle = length * width}}[/tex]
= 20 *4
= 80 mm²
Shape 3:
length = 5 mm
widht = 3 mm
Area of shape 3 = 5 * 3 = 15 mm²
Area of the composite shape = 207 + 80 + 15
= 302 mm²
