Answer:

√7x−49√x

Explanation:

First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:

√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7

... you can express √7x as √7⋅√x...

=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7

=√7⋅(√x)2−(√7)2⋅√x⋅7

... the operations squaring and taking the square root "eliminate each other"...

=√7⋅x−7⋅√x⋅7

=√7x−49√x

Hope that this helped!

Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR)
babymother [125]

Answer:

<em>The monthly payment is $450.71</em>

Step-by-step explanation:

<u>Financial Computing </u>

Given the loan amount A, the loan term t, and the APR (annual percentage rate), the montly payment is computed as

\displaystyle P=\frac{A}{f}

where f is

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

The provided data is

\displaystyle A=24,000

\displaystyle r=4.8\%

\displaystyle t=5\ years

Since the payments will be made monthly, the values of n and i are:

\displaystyle i=\frac{4.8}{100\times12}=0.004

\displaystyle n=5\times12=60\ months

Calculating f:

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

\displaystyle f=\frac{1-(1+0.004)^{-60}}{0.004}

\displaystyle f=53.25

Now for the payments:

\displaystyle P=\frac{24.000}{53.25}=450.71

\boxed{\displaystyle P=\$450.71}

In square ABCD, point M is the midpoint of side AB and point N is the midpoint of side BC. What is the ratio of the area of tria
Phoenix [80]

Answer:

Ratio of triangle AMN to square ABCD = 1/8

Step-by-step explanation:

area AMN = Area ABN - Area MNB

Where AB = BC = x

Area AMN = [ ½ *( x * ½x )] - [ ½( ½x * ½x)] = x²/8

Area of ABCD = x* x = x²

So therefore:

The ratio of area of triangle AMN to area of square ABCD would be

= (x²/8) / x²

=1/8
