Answer:
Approximately what will be saved will be 8.00
Step-by-step explanation:
Here, we want to know the amount that the customer will save
Firstly, we need to know the amount that all will cost
Mathematically, that will be;
24 + 16.12 + 10.5 = 50.62
The amount to be discounted is 15% of this
That will be 15% of 50.62
= 15/100 * 50.62
= 7.593
Answer:
x = {-4, 4}
Step-by-step explanation:
Subtracting 3 gives ...
5x^2 = 80
Dividing by 5, we get ...
x^2 = 16
Taking the square root gives the solutions ...
x = ±4
The smaller value of x is -4; the larger value is 4.
Answer:
B. W - 5
Step-by-step explanation:
The length is shorter than the width of the swimming pool by 5.
Width = W
Therefore the length of the pool would be W - 5
Answer:
Step-by-step explanation:
If (x+8) is a factor of f(x), then for some expression p, we have ...
f(x) = (x+8)p
Evaluated at x=-8, this gives ...
f(-8) = (-8+8)p = 0p
f(-8) = 0 . . . . must be true
_____
Similarly, f(8) = (8+8)p = 16p. This may or may not be zero, depending on the factors of p. The only offered statement that <em>must</em> be true is the one shown above.
