Answer:
$39.24
Step-by-step explanation:
Let's determine the sale price before tax:
0.40($60) = $24 is the discount, so
the sale price is $60 - $24, or $36.
Multiplying this result by 1.09 results in the total price, including tax. It is $39.24.

explanation:
60 x 0.85 = 51
Answer:
175 m
Step-by-step explanation:
We are given;
- The perimeter of a rectangle as 25 m
We are required to determine the new perimeter if the sides of the rectangle are multiplied by 7.
We know that;
Perimeter of a rectangle = 2(L+W)
Therefore, initially;
2(L+W) = 25 m
Hence;
L + W = 12.5 m
if the sides are multiplied by 7, then;
New length = 7L
New Width = 7W
Thus;
New perimeter = 2(7L+7W)
= 14 (L + W)
but, L + W = 12.5
Thus;
New perimeter = 14 (12.5)
= 175 m
Therefore, the new perimeter will be 175 m
Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
