Simplify. final answer should be written in standard form (a+b)(3a-b)(2a+7b)
algol13

we have

(a+b)(3a-b)(2a+7b)

step 1

Solve

apply distributive property

(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2

step 2

Multiply (3a^2-4ab-b^2) by (2a+7b)

6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3

answer is

<h2>6a^3+13a^2b-30ab^2-7b^3</h2>

Please guys i really need your help and please explain how you got it please
lina2011 [118]
The answer would be C because in order to find the area of a figure, you would need to multiply its height by its width. finding the area of a figure is the same as finding how many units are in a figure. because this is a square and all the sides are equal, by counting the total number of units, you can find the area.

Find the area of the shaded region
AlexFokin [52]

Answer:

7\pi cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = \pir²

A = \pi(3)²

A = 9\pi

Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)

A = \pir²

A = \pi(1)²

A = \pi

Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:

9\pi - \pi - \pi = 7\pi

So, the area of the shaded region is 7\pi cm²
