The answer is 5. If you need help remembering how to find the mean, you add up all the numbers given and then divide it by how many numbers there are so for example

8+6+4+8+3+1+5= 35

35 divided by 7

=5

Need some math help!!! <br> Factor the polynomial by grouping: 12p^3 − 21 p^2 + 28p − 49

Andru [333]

Answer:

$\left(4p-7\right)\left(3p^2+7\right)$

Step-by-step explanation:

$12p^3-21p^2+28p-49$

$\left(12p^3-21p^2\right)+\left(28p-49\right)$

$7\left(4p-7\right)$

$3p^2\left(4p-7\right)$

$7\left(4p-7\right)+3p^2\left(4p-7\right)$

$\left(4p-7\right)\left(3p^2+7\right)$

How do I solve this?

aksik [14]

Multiply the first equation by 2
4x-6y=16

Then add the equations to eliminate x
4x-6y=16
-4x+5y=-10

-y=6
y-=6

Plug the y value in
2x-3(-6)=8
2x+18=8
2x=-10
x=-5

Final answer: (-5,-6)

Which expression uses the associative property to make it easier to evaluate? (50points)

Naily [24]

The correct answer is option 4: $(8.\frac{1}{4}).\frac{3}{5}$

Step-by-step explanation:

Given expression is:

$8.(\frac{1}{4}.\frac{3}{5})$

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

$a.(b.c) = (a.b).c$

So applying the associative property on given expression

$8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}$

Hence,

The correct answer is option 4: $(8.\frac{1}{4}).\frac{3}{5}$
