If DE≅EF, CD = v + 45, and CF = 4v, what is the value of v?

irinina [24]

Answer:

<h2>since DE≅EF</h2>

CD=CF (cpct)

$v + 45 = 4v \\ 4v - v = 45 \\ 3v = 45 \\ v = \frac{45}{3} \\ v = 15$

Answer:

x = -15/2

Step-by-step explanation:

For this problem, we will simply use equation properties to solve for x.

2x - 5 = -20

2x - 5 + 5 = -20 + 5

2x = -15 ( Add positive 5 to both sides )

2x * (1/2) = -15 * (1/2)

x = -15/2 ( Multiply both sides by 1/2)

Hence, the solution to x is -15 / 2.

Cheers.

A rectangle has a length that is 9 feet less than four times its width. Its area is 90 square feet

kramer

Answer:

The length of rectangle is $15\ ft$

The width of rectangle is $6\ ft$

Step-by-step explanation:

Let

x-----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

$A=xy$

$A=90\ ft^{2}$

$90=xy$ -----> equation A

$x=4y-9$ -----> equation B

substitute equation B in equation A and solve for y

$90=(4y-9)y$

$4y^{2}-9y-90=0$

using a graphing calculator

The solution is

$y=6\ ft$

Find the value of x

$x=4y-9$ -----> $x=4(6)-9=15\ ft$
