The volume of a right triangular prism is 72 cubic feet. The height of the prism is 9 feet. The triangular base is an isosceles

Maslowich

Answer:

<h2>The area of the triangular base = 8 ft²</h2>

Step-by-step explanation:

The formula of a volume of a prism:

$V=A_BH$

$A_B-area\ of\ a\ base\\H-height$

We have

$V=72\ ft^3,\ H=9\ ft$

Substitute:

$72=9A_B$ <em>divide both sides by 9</em>

$8=A_B\to A_B=8\ ft^2$

Reptile [31]

Answer:

The option is D

$(n+4)^{2} - n^{2} = 8(n + 2)$

Step-by-step explanation:

Given

$(n+4)^{2} - n^{2} = 8(n + 2)$

put $n=1$ we get

$(1+4)^{2}- 1^{2}= 8(1+2)\\5^{2}- 1^{2}= 8\times 3 = 24$

Similarly,

put $n=2$ we get

$(2+4)^{2}- 2^{2} = 8(2+2)\\6^{2}- 2^{2}= 8\times 4 = 32$

put $n=4$ we get

$(4+4)^{2}- 4^{2} = 8(4+2)\\8^{2}- 4^{2} = 8\times 6 = 48$
