Answer:
(4+x)^2
Step-by-step explanation:
Rewrite 16 as 4^2
4^2+8x+x^2
Check the middle term by multiplying 2ab and compare the result with the middle term in the original expression.
2ab=(2)x(4)x(x)
Factor using the perfect square trinomial rule a^2+2ab+b^2=(a+b)^2, where a=4 and b=x

Answer:
37.7 ft²
Step-by-step explanation:
2×3.14×r=30.77
<em>Divide both sides by 2</em>
3.14×r=15.385
<em>Divide both sides by 3.14</em>
r≈4.9
3.14×r²
3.14×4.9²=
24.01×3.14≈
75.4
75.4÷2=
37.7
