4.–10x – x
5. 4 + 7(x + 3)
6. –k + 3(4k –1) + 2
7.6(–2y) – 9 + 4(–2y + 6)
8. 5(b – 4) + 12

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

you divide them and then you get the answer i took this class this year
