A = 2bs + b^2; where A = area of pyramid; b = base length; s = the slant height;
136 = 8s + 16 ;
8s = 120;
s = 15 inches;
Answer:
yes
Step-by-step explanation:
By definition, all sides are the same length, so the perimeter is simply the length of a side times the number of sides.
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
10x^5 + 5x^3 - 14x^2 - 7
= 5x^3(2x^2 + 1) - 7(2x^2 + 1)
= (5x^3 - 7)(2x^2 + 1)
Answer is D
(5x^3 - 7)(2x^2 + 1)
