Simplify 3 - b (7b + 2) + 3b - (11 - b)

nirvana33 [79]

Answer: -7b² + 2b - 8

Step-by-step explanation:

Given expression

3 - b (7b + 2) + 3b - (11 - b)

Expand parentheses and apply the distributive property if necessary

=3 - b · 7b - b · 2 + 3b - 11 + b

=3 - 7b² - 2b + 3b - 11 + b

Combine like terms

=-7b² + (3b - 2b + b) + (3 - 11)

= $\boxed{-7b^2+2b-8}$

Hope this helps!! :)

Please help number 7 and number 8

7. You are finding the area of the box. Not the cube, just a surface. Length times width of the surface. Eliminate other numbers and multiply

24.5×19.5

then

26×24.5

8. You are doing the same thing almost. Word problems are scary, but look for the numbers.

4inch ×8inch × 12inch

Find the volume
Multiply the volume by 3, that'd one answer
Devide the ORIGINAL volume by 2. don't divide the volume you multiplied by 3.
