factorize 2a^2+7a-15
Answer:
2a^2+10a-3a-15
2a(a+5)-3(a+5)
(2a-3) (a+5)
[tex] \huge\bf \pink {\underline{Solution :-}}[/tex]
[tex]2 {a}^{2} + 7a - 15[/tex]

What is the volume of the following triangular pyramid?
Answer:
The volume of the triangular pyramid
V = 566.66 in³
Step-by-step explanation:
Step(i):-
The volume of the triangular pyramid
[tex]= \frac{1}{3} X base area X height[/tex]
Base area = Area of the triangle
[tex]A= \frac{1}{2} X base X height[/tex]
Given the base of the triangle (b) = 17in
Given Height of the triangle (h ) =10 in
[tex]A= \frac{1}{2}( 17 ) (10) = 85[/tex]
The base area of the pyramid ( A) = 85 in²
Step(ii):-
Given the height of the pyramid (h) = 20in
The volume of the triangular pyramid
[tex]= \frac{1}{3} X base area X height[/tex]
The volume of the triangular pyramid
= [tex]= \frac{1}{3}( 85)(20) = 566.66[/tex]
Final answer:-
The volume of the triangular pyramid
V = 566.66 in³

Answer:
B. Ronit has 32 bananas. She started with 12 bananas. She bought 4 bunches of the same number (x) . How many bananas were in each bunch?
Step-by-step explanation:
This one is right because if you were to actually solve this problem the equation would be the exact same
She has 32 bananas (=32)
She started with 12 (12+)
and she bought 4 more bunches, but we don't know how many are in each bunch, which would be X
12+4x =32
An economy package of cups has 960 green cups. If the green cups are 40% of the total package, how many cups are in the package?
Answer: 2400 cups
Step-by-step explanation:
total # of cups = x
# of green cups = 960
% of green cups of total = 40%
# green cups/# of total cups = % of green cups/% of total cups
960/x = 4/10
9600 = 4x
2400 = x

Step 2: Solve for e
Subtract v on both sides: f - e = 2 - vSubtract f on both sides: -e = 2 - v - fDivide -1 on both sides: e = -2 + v + fWhat is the measure of angle x?
Answer:
x = 60°
Step-by-step explanation:
We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.
x + 30 + 90 = 180
x + 120 = 180
x = 60
Therefore, it is 60°.

Step-by-step explanation:
the numbers are all 3 apart
Answers:
(a) Yes this sequence is arithmetic.(b) The common difference is d = -3=================================================
Explanation:
This sequence is arithmetic because we're adding -3 to each term. This is the same as subtracting 3 from each term.
-13 + (-3) = -13 - 3 = -16
-16 + (-3) = -16 - 3 = -19
-19 + (-3) = -19 - 3 = -22
and so on. The term we add on each time is the common difference. It describes how the terms are spaced out, and how to generate each new term. The negative common difference is due to the sequence terms decreasing. An arithmetic sequence and a linear function are closely related ideas.

Given: 5x + 3 > 4x + 7.
Choose the graph of the solution set.
[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]
Step-by-step explanation:For the number line refer to the attachment :
A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-
[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]
This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .
Hence the first graph of the solution set represents the given linear inequality.Answer: B is correct
Step-by-step explanation: Tried a on the test, got it wrong, then tried b and got it right.

A town has a population of 14000 and grows at 5% every year. What will be the population after 14 years, to the nearest whole number?
Answer:
Step-by-step explanation:
Take 14000 and divide by 5 then multiply by 14.
Now the population of bacteria is two to the fourth power times two to the sixth power. Expressed as a power, how many bacteria is on the petri dish after 150 minutes?
Answer: 2¹⁰ bacteria
Step-by-step explanation:
There were originally 2⁴ bacteria in the dish.
After 150 minutes this number doubled 6 times which means it increased by 2⁶.
The number of bacteria will become:
= 2⁴ * 2⁶
= 2⁴⁺⁶
= 2¹⁰ bacteria
