Answer:
In bold below.
Step-by-step explanation:
let the shorter leg be x units long, then:
longer leg = x+4
and hypotenuse = x + x + 4 - 8 = 2x - 4 units.
By Pythagoras:
(2x - 4)^2 = x^2 + (x + 4)^2
4x^2 - 16x + 16 = x^2 + x^2 +8x + 16
2x^2 - 24x = 0
2x(x - 12) = 0
x = 12.
So the shorter leg = 12 units
Longer leg = 4 + 12 = 16 units and
Hypotenuse = 12 + 16 - 8 = 20 units.
Answer:
5 a b (5 b + 1)
Step-by-step explanation:
Factor the following:
25 a b^2 + 5 a b
Factor 5 a b out of 25 a b^2 + 5 a b:
Answer: 5 a b (5 b + 1)
It cannot be simplified, it is already reduced its broken down into lowest terms .
If the Fraction is 4/6 then it is 2/3. I got that by dividing both the numerator and the denominator by 2.
