Solution:
Let's verify each option to see which is correct.
<u>Option A</u>
Two subtracted from the quotient of seven divided by b.
- => 7/b - 2 = 7(b - 2) [False]
<u>Option B</u>
Seven added to difference of b minus two.
- => 7 + (b - 2) = 7(b - 2) [False]
<u>Option C</u>
The quotient of seven divided by b minus two.
- => 7/b - 2 = 7(b - 2) [False]
<u>Option D</u>
Two subtracted from seven times b
- => 7b - 2 = 7(b - 2) [False]
<u>Option E</u>
The product of seven and the difference of b minus two
- => 7 x (b - 2) = 7(b - 2) = 7(b - 2) [True]
Option E is correct.
- A rectangle has a perimeter of 44 inches and an area of 72 square inches.
- Perimeter = 44 inches, area = 72 square inches.
- Let the length and breadth be l and b respectively.
- We know, perimeter of a rectangle = 2(l + b)
- Therefore,
- 2(l + b) = 44
or, l + b = 22
or, b = 22 - l ...(i)
- We know, area of a rectangle = lb
- Therefore,
- lb = 72
- Putting (i) in b, we get
- l(22 - l) = 72
or, 22l - l^2 -72 = 0
or, l^2 - 22l + 72 = 0
or, l^2 - 4l - 18l + 72 = 0
or, l(l - 4) - 18(l - 4) = 0
or, (l - 4)(l - 18) = 0
or, l = 4 or l = 18
- Therefore, if the length is 4 inches, then the breadth is (22-4) inches, i.e., 18 inches.
- And if the length is 18 inches, then the breadth is (22-18) inches, i.e., 4 inches.
<u>Answer:</u>
<u>B)</u><u> </u><em><u>4</u></em><em><u> </u></em><em><u>inches </u></em><em><u>and </u></em><em><u>1</u></em><em><u>8</u></em><em><u> </u></em><em><u>inches.</u></em>
Hope you could get an idea from here.
