1.
3n + 5 = 6
3n = 6 - 5
3n = 1
n = 1/3

2.
4 + 5x = 1
5x = 1 - 4
5x = -3
x = -3/5

3.
4y - 15 = -10
4y = -10 + 15
4y = 5
y = 5/4

4.
3 - 4d = 13
-4d = 13 - 3
-4d = 10
d = -10/4
d = -5/2

5.
8 = 9x - 7
8 + 7 = 9x
15 = 9x

Factor each expression by factoring out the common binomial <br><br> 5a(y + 4) + 8(y + 4)

Tems11 [23]

Answer:

Factoring the term $5a(y + 4) + 8(y + 4)$ we get $(y+4)(5a+8)$

Step-by-step explanation:

We need to factor the term: $5a(y + 4) + 8(y + 4)$

Factoring:

$5a(y + 4) + 8(y + 4)$

Taking (y+4) common

$(y+4)(5a+8)$

It cannot be further factored.

So, Factoring the term $5a(y + 4) + 8(y + 4)$ we get $(y+4)(5a+8)$
