Answer = B - 33yd
Because the perimeter is all the sides added up so you do length + length + width + width = 11.5 + 11.5 + 5 + 5 = 33
If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2
1-2 = -1
If that's what u mean
Answer:
L=7.94 feet, W=9.88 feet
Step-by-step explanation:
perimeter=78 feet
LxW=78
2L-6=W
substitute
Lx(2L-6)=78
2L^2-6L=78
2L^2-6L-78=0
factor
(2L-15.86)(L+4.95)=0
2L=15.88, L=7.94
L=-7.94 feet
Answer:
y=-8
Step-by-step explanation:
-8y-16=48
+16+16
