Answer:
Step-by-step explanation:
Simplify the left side.
<u>Multiply both numerator and denominator by the conjugate of the denominator:</u>
- (√3 - 1)/(√3 + 1) =
- (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =
- (√3² - 2√3 + 1)/(3 - 1) =
- (10 - 2√3)/2 =
- 5 - √3
<u>Compare this to the right side to get:</u>
First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
The perimeter of the parallelogram is 56 ft Option C.
Step-by-step explanation:
Given,
The length (l) of the parallelogram = 20 ft
The width (b) of the parallelogram = 8 ft
To find the perimeter of the parallelogram.
Formula
The perimeter of the parallelogram = 2(l+b)
So,
The perimeter of the parallelogram = 2(20+8) ft = 56 ft
The length of the 8 races in meters is 24000 meters
