Answer:

5

Step-by-step explanation:

1) N is equal to -6 and you are challenge to find the value in the expression n²+5n -1.

so we have:-

n= -6

the expression is n²+5n-1

2) next we substitute the value of n= -6 in the expression n²+5n-1. this means wherever we see 'n' in the expression, we replace it with '- 6 ' so instead of writing n we will write the value -6. thus we have:-

(-6)² + 5(-6) - 1

36+ (-30) - 1

36-30-1

W=x
L=2x+17

Double everything since we need to lengths and two widths to find the perimeter

2x+17+2x+17+x+x = 76
Combine like terms

6x+34=76
Solve for x
First step is subtract 34 from both sides

6x=42
Next you divide both sides by 6 in order to get x by itself

X=7

Now you plug in 7 into the x’s in length and width

W=7 cm
L=31 cm

THE WIDTH IS 31 CM

Check:

7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.
