Answer:

32x+20

Step-by-step explanation:

If you use distributive property you would multiply each number by 4. 4 times 8x is 32x and 4 times 5 is 20, and when you put those together you get 32x+20!

I hope this helps, and have a great day!

A car dealer will sell you a used car for $6,498 with $798 down and payments of $162.51 per month for 48 months. what is the int

Mkey [24]

Answer:

Interest rate is 1.4% and APR is 16.8%.

Step-by-step explanation:

Given,

The original cost of the car = $ 6,498,

Down payment = $ 798,

So, the present value of loan, P.V. = original cost - down payment

= $ 6,498 - $ 798 = $ 5700,

Now, the monthly payment, P = $ 162.51,

Number of months, n = 48,

Let r be the monthly interest rate,

Since, monthly payment formula of a loan,

$P=\frac{PV(r)}{1-(1+r)^{-n}}$

$162.51=\frac{5700r}{1-(1+r)^{-48}}$

By graphing calculator,

$r=0.014= 1.4\%$

Hence, interest rate = 1.4%,

And, APR = 12 × 1.4% = 16.8%.

The value of the solid’s surface area is equal to the value of the solid’s

Katen [24]

Answer:

1. x = 15 in

2. x = 8 m

Step-by-step explanation:

1. Given:

length = 10 in

width = 3 in

height = x in

surface area of the rectangular prism = its volume

Required:

Value of x

Area = 2(wl + hl + hw)

Volume = l*w*h

Therefore:

2(3*10 + x*10 + x*3) = 10*3*x

2(30 + 10x + 3x) = 30x

2(30 + 13x) = 30x

60 + 26x = 30x

Subtract 26x from both sides

60 + 26x - 26x = 30x - 26x

60 = 4x

Divide both sides by 4

60/4 = 4x/4

15 = x

x = 15 in

2. Given:

length = 8 m

width = 4 m

height = x m

surface area of the rectangular prism = its volume

Required:

Value of x

Area = 2(wl + hl + hw)

Volume = l*w*h

Therefore:

2(4*8 + x*8 + x*4) = 8*4*x

2(32 + 8x + 4x) = 32x

2(32 + 12x) = 32x

64 + 24x = 32x

Subtract 24x from both sides

64 + 24x - 24x = 32x - 24x

64 = 8x

Divide both sides by 8

64/8 = 8x/8

8 = x

x = 8 m
