Answer:
$119.57
Step-by-step explanation:
We have to find present value of annuity to find the monthly payment.
Given,
Present value, PV = $4,000
Down payment = $4,000 × 10% = $400
Remaining present value = $(4,000 - 400) = $3,600
Interest, i = 12% = 0.12
As we need monthly payment, the interest rate will be monthly = 0.12/12 = 0.01.
Number of period, n = 3
monthly payment, m = 12
We know,
Present value of annuity = PMT × 
$3,600 = PMT × 
or, $3,600 = PMT × 30.1075
or, PMT = $119.57
Monthly payment should be $119.57
Since the polys are similar, the following equation of ratios is true:
7/8 = x/3. Cross multiplying produces 21=8x, and so x = 21/8 (answer)
Answer:
no but I can tell you it's no fun
First you gotta remove all parentheses by multiplying the factors next remove all grouping if the terms are containing exponents then you combine all terms and lastly you combine the constants
