Answer 2

Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.

2.Use the exponent rule to remove grouping if the terms are containing exponents.

3.Combine the like terms by addition or subtraction.

4. Combine the constants

Step-by-step explanation:

$8(5w+7) + 9 ( 4w- 7)$

The first thing we do is distribute

$8(5w+7)& 9(4w-7)$

We distribute what is outside the parenthesis to everything that is inside the parenthesis

so for 8(5w+7) we do $8x5w = 40w$ and $8x7 = 56$

so for 9  So  9(4w−7) turns into 36w+63

so now we have 40w+56+36w+−63

now combine like terms

(40w+36w)+(56+−63)=?
