Answer:30
Step-by-step explanation:the perimeter is 26 and the length is 7 more than the width so you subtract 14 for both the sides of the rectangle from the perimeter and are left with 12 so you divide that by 4 for the 4 sides of the rectangle and get 3 so the width is 3 and the length is 10.
17.76(5) = 88.15 + 27.52 = 115.67
Answer is A
Answer:
153.86
Step-by-step explanation:
use pi x radius squared
Answer:

Step-by-step explanation:
So we have the equation:

First, let's determine the domain restrictions. Recall that the radicand cannot be negative. In other words, it must be greater than or positive than 0. Thus:

Subtract 6 from both sides:

What this means is that our solutions must be greater than or equal to -6. If not, we ignore them.
So, let's subtract 5 from both sides from the original equation:

Square both sides:

Subtract 6 from both sides:

138 is greater than -6, so 138 is a solution and is the only solution.
And we're done!
