Answer:
7: 12 / 6 <- answer
9: 12 / 2 <- answer
Answer:
Step-by-step explanation:
<u>Given</u>
- Rectangle with sides of 20 in and x+2 in and perimeter of 68 in
<u>Perimeter = 2(l + w)</u>
- l = 20 in, w = x + 2 in, P = 68 in
<u>Substitute values in perimeter formula</u>
- 68 = 2(20 + x + 2)
- 34 = x + 22
- x = 34 - 22
- x = 12 in
<u>Then, the value of width is</u>
<u>Area of rectangle</u>
<u>Area of circle</u>
- A = πr² = 3.14*7² = 153.86
<u>Shaded area </u>
- 280 - 153.86 = 126.14 in²
Answer:
y = 35x
and 350
Step-by-step explanation:
This problem's quite similar to the last question with the only difference being the 2nd row changed
So I <em>think </em>that the answers should be the same
