4.) 3x³ for x=-3

a 728 b -81 c 81 d -729

5.) 4r² - 2s³ for r=1 and s=5

will give 10 ! the formula for the area of a triangle is a=1/2bh , where b is the base of the triangle and h is the height of the triangle. what is the base of the triangle with an area of 30 ft² and height of 12ft?

a 3ft

b 2.5ft

c 5ft

d 10ft

will give 5 !

find the area of the figure

square: s=4 2/5

a 19 9/25 in²

b 1 19/25 in²

c 3 13/25 in²

d 11/25 in²

will give 5 !

use the formula d = rt to find the following: r for d= 15.4 mi and t=1.4 h

a 16.8 mi/h

b 0.09 mi/h

c 21.56 mi/h

d 11 mi/h

will give 5

evaluate to gret the given value

( -h-3j)²/h for h=3 and j= -5

a 48

b 8

c 108

d -28

will give 10 !

solve the formula for the indicated variable

m = c - ab for a

a a = m/cb

b a = c/b - m

c a = m-c/b

d a = c-m/b
