Answer:
c
Step-by-step explanation:
if I understand this right, then the expression is
2×sqrt(28) - 5×sqrt(63)
let's look for squared factors in the numbers under the square roots.
28 = 4×7 (4 is a squared number)
63 = 9×7 (9 is a squared number)
so,
2×sqrt(4×7) - 5×sqrt(9×7) =
= 2×2×sqrt(7) - 5×3×sqrt(7) = 4×sqrt(7) - 15×sqrt(7) =
= (4 - 15)×sqrt(7) = -11×sqrt(7)
Im pretty sure the answer is 2x^3-x^2+13x-6/x-3
Answer:
14
Step-by-step explanation:
1/2x = 1/7x + 5
1/2x - 1/7x = 5
7/14x - 2/14x = 5
5/14x = 5
x = 5 * 14/5
x = 14
The change in value was 8% which amounts to $1630
Further explanation:
The change in value is calculated by using the initial price and selling price of the car.
Given
Purchase Price = P = $21330
Selling Price = S = $19700
As the selling price is less than the purchase price, Cindy had loss.

Percentage of loss will be calculated as:
