Answer: 1.35, 2.5, 1.8
Step-by-step explanation:
The name of parts of body???
Step-by-step explanation:
- (x²y)(x³y⁴)
- x²y×x³y⁴
- x²×x³×y×y⁴
- x^2+3×y^1+4
- x⁵×y⁵
- x⁵y⁵
X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter
So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10
If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base
You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.
(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
