5 0

N+3=5
n+3-3=5-3 (subtract 3 on both sides)
n=2
to check you substitute n with 2 and you get 2+3=5 (5=5)

4 0

So what they are telling you is that 5 is three higher than the variable n.
So n = 5-3
so n is 2.

Answer:

-1 and -5

Step-by-step explanation:

m^2 + 6m + 5 = 0 is factored to: (m + 1)(m + 5) = 0.

The zero product property states that one of the represented parenthesis must equal zero to satisfy the right side of the equation.

(m + 1) = 0

(-1 + 1) = 0

This means that one of the values for m is -1.

(m + 5) = 0

(-5 + 5) = 0

This means that one of the values for m is -5.

Moreover, the value of m by factoring is -1 and -5

L=w+2 and 2w+2l=40

Substitute length for w+2 in perimeter formula.

2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9

l=w+2
l=9+2
l=11

a=lw=11*9=99 meters
