In order for the triangle to be isosceles, we have to set two lengths of the triangle equal to each other. 

Let's take the lengths 5x-12 and x+20 and set them equal to each other. 

5x - 12 = x + 20 

Combine like terms by moving them over to their respective sides.

Subtract x from both sides of the equation. 

4x - 12 = 20 

Add 12 to both sides of the equation. 

4x = 32 

Divide both sides by 4. 

x = 8 

Check your answer by substituting. 

5x - 12 = x + 20

5(8) - 12 = 8 + 20

40 - 12 = 28 

28 = 28

Solution: x = 8

What is the total amount that First Consumer Bank will receive after lending Jane $7,000 for three years at an interest rate of
8_murik_8 [283]
Given:
principal = 7,000
interest rate = 5% compounded annually
term = 3 years

A = P (1 + r/n)^nt

A = future amount to be received by First Consumer Bank
P = loan principal
r = rate
n = number of times compounded in a year
t = term

A = 7,000 ( 1 + 5%/1)^1x3
A = 7,000 (1.05)³
A = 7,000 (1.157625)
A = 8,103.375

First Consumer Bank will receive 8,103.375 from Jane after lending 7,000 for 3 years compounded annually at 5%.

What is the center and radius of the circle?<br> (x-2)2 +(y+3)2 = 49
ivolga24 [154]

Answer:

Center: 2, -3

Radius: 7

Step-by-step explanation:

The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.

The radius is equal to the square root of the constant on the other side.

The square root of 49 is 7.
