Step-by-step explanation:
x*x=x^2
x*9=9x
x*3=3x
9x+3x=12x
9x3=27
x^2+12x+27
Answer:
-8 degrees
Step-by-step explanation:
-4 minus 7 degrees add 3 degrees
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
