Answer:
w(2w+4)
Step-by-step explanation:
we know A = l * w
and Perimeter = 2l + 2w
we want to find l in terms of w
2l + 2w = 6w + 8
2l = 4w + 8
l = 2w + 4
so A = w * (2w + 4)

When u plug in what the x variable is in each equation, you figure out what y equals to.
1.y=(2)^3 +1 so y=8+1 so y=9
2.y=(-2)^3 +1 so y=-8+1 so y=-7
Answer:
27
Step-by-step explanation:
break shape into two parts
rectangle - 4*3=12
triangle 6*5/2 = 15
add rect and triangle tgt - 12+15=27
First multiply 2/3*9x=6x
then multiply 2/3*-6=-4
this being 6x-4.
then multiply 4*x=4x
then multiply 4*2=8
this being 4x+8.
so we have 6x-4=4x+8+2
we add the 8+2=10
6x-4=4x+10
now we subtract the x to both sides (choose 4x)
2x-4=10
now we add 4 to both sides.
2x=14
we divide 2 to both sides.
we get x=7
final answer:x=7
