Which of the following is equal to the average of (x+2)^2 and (x-2)^2

Digiron [165]

expand factors, sum like terms and divide by 2

(x + 2)² + (x - 2)² = x² + 4x + 4 + x² - 4x + 4 = 2x² + 8

$\frac{1}{2}$ (2x² + 8 ) = x² + 4 → C

In the 1980s an average mortgage rate was around 18.5 how much less per month would a 150000 30 year mortgage by today if the cu

lianna [129]

Answer:

$1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

125 x 0.35 ( work shown

weqwewe [10]

Answer:

Step-by-step explanation:

125/x=100/0.35

(125/x)*x=(100/0.35)*x - we multiply both sides of the equation by x

125=285.71428571429*x - we divide both sides of the equation by (285.71428571429) to get x

125/285.71428571429=x

0.4375=x

x=0.4375

now we have:

0.35% of 125=0.4375

Solve the proportion. a. 4/x = 9 b. 7.5/26 = 75/p

lina2011 [118]

ANSWER:

The values of x and p after solving given equations are 0.445 or $\frac{4}{9}$ and 260 respectively..

SOLUTION:

Given, two proportions are $\frac{4}{x}$ =9 and $\frac{7.5}{26} = \frac{75}{p}$

We need to solve the given two proportions.

Let us solve the first proportion, $\frac{4}{x}$ = 9

$\frac{4}{x} = \frac{9}{1}$

On cross-multiplication, we get

4 $\times$ 1 = 9x

4 = 9x

x = $\frac{4}{9}$

x = 0.445

Now, let us solve the second proportion $\frac{7.5}{26} = \frac{75}{p}$

$\frac{\frac{75}{10}}{26}=\frac{75}{p}$

$\frac{75}{10 \times 26} = \frac{75}{p}$

$\frac{1}{260} = \frac{1}{p}$

On cross-multiplication, we get

p = 260

Hence, the values of x and p after solving given equations are 0.445 and 260 respectively.
