I don’t know I suck at math sadly
2.8 because the tenths place is right after the decimal point.
To find the percent discount you will write the following equation:
x% of 60 is 18
<u>60x</u> = <u>18</u>
60 60
x = 0.3
The discount is 30%.
Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.
