Answer:
x = - 2√2
x = -2
Step-by-step explanation:
A . 5 + x² = 2 x² +13
5 + x² - 2 x² - 13 = 0
- x² -8 = 0
- x² = 8
x² = -8
x = - √8
x = - 2√2
B . 5 + x³ = 2 x³ + 13
5 + x³- 2 x³ - 13 = 0
- x³ -8 = 0
-x³ = 8
x³ = -8
x = - ∛8
x = -2
Answer:
The rate of sales tax is 6%.
Step-by-step explanation:
First you must subtract 12.50 from 13.25
This brings you to .75
Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.
K/3 + 4 = 10
K/3 = 10 - 4
K/3 = 6
K = 6x3
K = 18
