Answer:
(a - b)² = 6
Step-by-step explanation:
The expansion of (a - b)² using FOIL is
(a - b)² = a² + b² - 2ab ← substitute given values
= 10 - 2(2)
= 10 - 4
= 6

Mark has a bag with different flavors of candy. The bag contains 4 cherry, 3 lemon, 7 watermelon, and 2 grape candies. Which of the following shows the complement of selecting a grape candy?
The complement of selecting a grape candy is D. 7:8.
What is the complement in probability?The complement of a choice is the ratio of not choosing the specified item in preference to others.
The chance of choosing a grape candy is 1/8 or 1:8. The complement of choosing a grape candy is 7:8 or (1 - 1/8).
The complement of a choice is the opposite probability of choosing an event.
Items Number Ratio
Cherry 4 4/16
Lemon 3 3/16
Watermelon 7 7/16
Grape candies 2 2/16
Total 16
The ratio of grape candies = 2/16 or 1:8
The ratio of not choosing grape candies = 14/16 or 7/8
Thus, the likelihood of failing to choose a grape candy is Option D.

Chau made $252 for 18 hours of work. At the same rate, how much would he make for 9 hours of work?
Answer:
$126
Step-by-step explanation:
$252/$18=$14 dollars per hour.
now take 14*9 and you get $126.
Answer:
$126
Step-by-step explanation:
Okay, so to solve this question, we need to get from 18 (hours) to 9. To do this, we obviously divide 18 by 2. Since we did this, we now have to do the same thing with the other side ($252.) 252 divided by 2 is 126. This means that if Chau made $252 in 18 hours, he will make $126 in 9 hours.
Have a nice day! :)
Which expression are equivalent to 4+4x+2y+x-y)?

Step-by-step explanation:
Alexandra worked 5 hours on Monday, 4.5 hours on Tuesday, and 2.5 hours on Wednesday. Which is closest to the mean number of hours she worked over the three-day period?
5 + 4.5 + 2.5 = 12 ÷ 3 = 4
how I know mean is when you add each together then divide it by how many things you added together so we added 3 things together so just divide your answer by 3.
Solve the equation
5x - 12 = 3 (x+ 6)
Answer:
x=15
Step-by-step explanation:
5x-12=3(x+6) = 5x-12=3x+18
+12 on both sides
5x=3x+30
-3x on both sides
2x=30
2x/2=x
30/2=15
x=15

Answer:
x = √53
Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.
(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)
Step-by-step explanation:
1. Plug in the numbers in the pythagorean theorem.
2^2 + 7^2 = c^2 (remember, each variable is squared)
2. Simplify.
4 + 49 = 53
Since each variable in the pythagorean theorem is squared, the side value would be √53.

The derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).
What is trigonometric identity?The trigonometric identities is the relationship between the different trigonometric ratios.
These trigonometric identities are the basic formulae that are true for all the values of the reference angle.
For the given situation, the derivation for the tangent sum identity is given in the table below.
The derivation follows the steps,
[tex]\dfrac{sin (x+y)}{cos (x +y)}[/tex]
we know that,
sin (x + y) = sin x cos y + cos x sin y
cos (x + y) = cos x cos y - sin x sin y
Substitute;
[tex]\dfrac{sin x cos y + cos x sin y}{cos x cos y - sin x sin y}[/tex]
Divide each term by cos x cos y
[tex]\dfrac{\dfrac{sin x cos y}{cos x cos y} + \dfrac{cos x sin y}{cos x cos y} }{\dfrac{cos x cos y}{cos x cos y} - \dfrac{sin x sin y}{cos x cos y} }[/tex]
Now, [tex]\dfrac{tan x + tan y}{1 - tan x tan y}[/tex]
Hence we can conclude that the derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).
