5. if x=3 then replace x with 3. 3^2 is 9, 1/3 of 9 is 3, 3+2 = 5
Answer:
2.25
Step-by-step explanation:
because you have to divide 32 by 14 2/9 resulting in the the 14 2/9 to be 128/9 and then flipped, 9/128. Afterwards, cross out the the 32 and 128 since 32 is a factor of 128 to get 1 and 4.Then apply mutiplication 1/1 * 9/4= 9/4 or 2 1/4= 2.25

Explanation:
The square base of the pyramid has four sides with length 15 inches, making its perimeter four times that, or 60 inches. The slant height is
112×60=90 inches.
Therefore, the area of the base is B=152=225 square inches.
Each of the four lateral triangles has area 12⋅15⋅90=675 square inches.
The total surface area is 225+4⋅675=2,925 square inches.
