Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ± 
= ± 8
Solutions are x = 8 and x = - 8
Answer:
its A
Step-by-step explanation:
Complimentary means 90 degree angle so 90-41.4= the complimentary angle which is 48.6. Supplementary means 180 degrees so 180-41.4= the supplementary angle which is 138.6..
Answer: 84.14
Step-by-step explanation:
Area of the rectangle is L*W=B*H
14*5=70
To find the area of the half circle we must use the formula pi r^2/2
r=radius
and the radius is 6 because we add 4 and 4 and need to get to 14
because the line below it is 14 and it is a rectangle so the lengths are the same.
Diameter=6
So radius =3
pi (3)^2/2=
9/2 pi + 70=
84.14
