What is the volume of the pyramid? a. 139 cm3 b. 484 cm3 c. 142 cm3 d. 420 cm3

V = 1/3 B * H where B is the area of the base and H is the height

to find the base , we find the area

B = s^2 where s is the side length

so

V = 1/3 s^2  *H

V = 1/3 * 11^2 * 12

V = 1/3 * 121 * 12

V = 484 cm^3

Choice B

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
