Answer:
Step-by-step explanation:
Perimeter = 2(l + w)
l = 8.5cm, perimeter = 24cm
24 = 2(8.5 + w)
Dividing through by 2
24/2 = 8.5 + w
12 = 8.5 + w
W = 12 - 8.5
W = 3.5cm
Answer:
The other factor of the polynomial is (5x -6)
Step-by-step explanation:
Here, we want to find the other factor of this binomial expression
To find the other factor, we simply proceed to divide the polynomial by the binomial
That would be;
(10x^2 + 18x - 36)/(2x + 6)
= 5x - 6
Answer:

And on this case we can use the product rule for a derivate given by:

And replacing we have this:

Answer:
The value of f is 80.6.
Step-by-step explanation:
We are given the equation and asked to solve for f.
If we are given a fraction with a variable in the numerator, we can multiply both sides of the equation by the denominator to isolate it.
For example, if you look at this equation:

We can multiply both sides by 26 to get the a by itself so the equation can be solved.

Therefore, we can apply this same technique to the equation 

Therefore, the value of f is 80.6.
