Answer:
5x^2 +8x-4
Step-by-step explanation:
(5x - 2) * (x + 2)
We can FOIL
first: 5x*x = 5x^2
outer : 2*5x = 10x
inner: -2x
last : -2*2 = -4
Add these together
5x^2 +10x-2x-4
5x^2 +8x-4
Answer:
21
Step-by-step explanation:
In order to find the answer, plug in 5 for z.
The first thing you do is distribute. So multiply -7 to n and 6 to get -7n-42=-91 add over -42 to -91 to get -7n=-133 then divide by 7 on both sides and you get n=19
