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:

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

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

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

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

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

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

A flea weighs 8 decigrams, and an ant weighs 3 milligrams. How much more does a flea weigh than an ant?

Tasya [4]

It should be 7.97 decigrams, since you want to convert 3 milligrams to decigrams (0.03), it is asking "How much more" which means you subtract. 8 subtracted from 0.03 is 7.97.

Hope this helps :)

What is the midpoint of QR. Q(2,4) and R(-3,9)

Eduardwww [97]

Answer:

The answer is

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

Q(2,4) and R(-3,9)

The midpoint is

$M = ( \frac{2 - 3}{2} \: , \: \frac{9 + 4}{2} ) \\$

We have the final answer as

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Hope this helps you
