Your answer is simple, it's x = 0
Calculate circumference. You can do the math mentally with area & perimeter,but circumference is much more complex
Answer:
A) L = W + 6
B) L * W = 167 OR L = 167 / W
Substituting B) into A)
167 / W = W + 6
Multiplying both sides by "W" we get
167 = W^2 + 6W
W^2 + 6W -167
Solving by the quadratic formula
Width = 10.266
Length = 16.266
Step-by-step explanation:
Tax
$350x0.07
=$24.50
(0.07 is the 7% tax in decimal form)
Total cost
$350+$24.50
=$374.50
OR
$350x107%
=$374.50
1.07 is the table cost (100%) plus the sales tax (7%)
The table costs $374.50 with tax.
Use this formula: A = P(1 + r/n)^nt, where A is the amount after interest (what you are solving for), P is the amount you invested originally, r is the rate at which it was invested in decimal form, n is the number of times the compounding occurs each year, t is the time in years it is invested. It would look like this: A = 500(1 + [.06/12])^12*5. Do inside the parenthesis first to get 1 + .005 = 1.005. Now raise that to the 60th power (12 times 5 is 60) to get 1.34558. Now multiply that by the 500 out front to get a total amount of $674.43
