Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5

The semi-circle's area is $\pi$ $3^{2}$ /2 = 14.14

Combined, you get an area of 10.5 + 14.14 = 24.64 $yd^{2}$

Answer:

17*2^11

Step-by-step explanation:

Lets start by remembering two property of power.

$x^{m} * x^{n}= x^{n+m}$

$(x^{m})^{n}= x^{m*n}$

That is important to remember since 4= 2^2. Hence, the given problem can be written as the following

$-2*(2^{2} )^{5}+9*2^{2}*(2^{2} )^{5} \\-2*2^{10}+9*2^{2}*2^{10}\\ -2^{11}+9*2^{12}\\ -2^{11}(-1+9*2)=-2^{11} (17)$
