The length of a rectangle is 5 cm more than twice a number. the width is 4cm less than the same number. if the area of the recta
lana [24]
A = Lw (area of rectangle is length times width)
A = 15 (Area is 15)
L = 2x + 5 (length is 2 times a number plus another 5)
w = x - 4 (width is 4 less than that number

Plug in the values:
15 = (2x + 5)(x - 4)
FOIL
15 = 2x2 - 8x + 5x - 20
simplify:
15 = 2x2 - 3x - 20
Subtract 15
0 = 2x2 - 3x - 35
Factor out the quadratic. We know that one number has to be 7 and the other 5 so that they multiply together to make 35, and that one of them has to be negative so that it's actually -35.
That means we have m * n = -35
We also need it set up so that so that 2m + n = -3:
2 * -5 + 7 = -3
0 = (2x + 7)(x - 5)
So:
0 = 2x + 7, or 0 = x - 5
x = -7/2 or 5
We cannot have a negative length, so x = 5

Check:
15 = (2 * 5 + 5) (5 - 4)
15 = 15 * 1
15 = 15

The lengths of the three sides of a right triangle are 25,15,20. Which equation correctly expresses the relationship between the
aleksklad [387]

Answer:

Option C. 15^2 + 20^2 = 25^2

Step-by-step explanation:from the question, we obtained the following:

The sides = 25, 15, 20

Since it is a right angle triangle, 25 is the longest side. Therefore their relationship is:

15^2 + 20^2 = 25^2
