2.)7x;x=-5
7(-5)
35
3.)y=1-2x;x=9
y = 1 - 2(9)
y = 1 - 18
y = -17
4.)y=3x+2;x=0.5
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5
5.)y=2x^3;x=3
y = 2(3^3)
y = 2(3)(3)(3)
y = 2(27)
y = 54

Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)
Y^2 + 4y - 32 = 0
y^2 - 4y + 8y - 32 = 0
y(y - 4) + 8(y - 4) = 0
(y + 8)(y - 4) = 0
y + 8 = 0 or y - 4 = 0
y = -8 or y = 4.
