Answer:
Real numbers = 39 and 9
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c = 0
Given the following data;
a = 1
b = -43
c = 306
Quadratic equation formula is;
Substituting into the equation, we have;
Therefore, the two real numbers are 39 and 9.
The quadratic equation now becomes;
x² - 43x + 306 = (x - 39)(x - 9) = 0
Answer:
$297.50
Step-by-step explanation:
If she earns 105 for three hours, she would be earning $35 an hour.
105/3=35
If she works 8.5 hours, to find the amount you would multiply the hourly rate ($35) by 8.5. So, the answer is
8.5x35=$297.50
32 is 40% of?
32/40
32 ÷ 40 = 0.8
0.8 × 100 = 80
80
32 is 40% of 80.
24.
This is because if we double the base and the height in the area equation it will raise any number by a factor of 4.
:
The area.
She is trying to find how to cover it, which would be the area of the floor.
