kondor19780726 [428]

Answer:

The sides are

6

inches,

8

inches and

10

inches

Explanation:

I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'

In this case the question can be answered. If

x

is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4

x+3/4x+3/4x+4=24

10/4x=20

x=8

Then the shortest side is 6and the longest side is 10

F(-1) f(x) = -3x2 + 2x - 7
egoroff_w [7]

Answer:

f(-1) = -12

Step-by-step explanation:

<u>Step 1:  Set x to -1 and solve</u>

<u />f(x) = -3x^2+2x-7

f(-1) = -3(-1)^2+2(-1) - 7

f(-1) = -3(1) - 2 - 7

f(-1) = -3 - 2 - 7

f(-1) = -12

Answer:  f(-1) = -12

She will receive $25.

They will take her claim and subtract the comprehensive deductible from it (comprehensive is the insurance that covers theft, not collision).
