Find the other leg
24^2 - 7^2 = leg^2
576 - 49 = leg^2
leg^2 = 527
leg = 22.96
Perimeter = 24 + 7 + 22.96 = 53.96
Multiply
ignoring the square root sign for a moment to get
. Simplify
to get 20. so, your answer is B.
Answer:
4
Step-by-step explanation:
Answer:
(4x + 5)(4x - 3)
Step-by-step explanation:
Given
16x² + 8x - 15
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 16 × - 15 = - 240 and sum = + 8
The factors are + 20 and - 12
Use these factors to split the x- term
16x² + 20x - 12x - 15 ( factor the first/second and third/fourth terms )
= 4x(4x + 5) - 3(4x + 5) ← factor out (4x + 5) from each term
= (4x + 5)(4x - 3) ← in factored form
We can simply set the two equations equal to each other:
60x+10=40x+70
We subtract 40x+10 from both sides to get:
20x=60
Divide by 20 to find that x=3. Substitute this back into either equation to find the amount of miles - using the first, 60*3+10=190, so the answer is D.
