What substitution should be used to rewrite 6(x + 5)2 + 5(x + 5) – 4 = 0 as a quadratic equation?
- (x+5)
- (x - 5)
Ou-(x + 5)2
u = (x - 5)2

x+5 is replaced

Step-by-step explanation:

6(x + 5)^2 + 5(x + 5) – 4 = 0

Replace x+5 with m

6(m)^2 + 5(m) – 4 = 0

Now this is a quadratic equation

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

5+2x=a
