Hi,
Work:
Equation;

First add up numbers and distribute 9 over parenthesis.

Second: collect like terms.

Move variable 59p to left side and change its sign.

Then move constant 123 to right side and change its sign.

Calculate the difference.

Divide both sides of equation by 59.

Hope this helps.

Answer:
- The smaller one is x = 3
- and the larger one is x = 6
Step-by-step explanation:
A "critical number" is a function argument where the function has zero or undefined slope. A polynomial function never has undefined slope, so we're looking for the x-values where f'(x) = 0.
A graphing calculator easily shows the points that have zero slope. They are found at x = 3 and x = 6.
_____
Setting the derivative to zero is another way to find the points with zero slope:
f'(x) = 6x^2 -54x +108 = 6(x^2 -9x +18) = 6(x-3)(x-6)
The derivative will be zero where the factors are zero, at x=3 and x=6.
The critical numbers are x=3 and x=6.
Answer:
C. 5
Step-by-step explanation:
Triangle BED is enlarged by scale factor 4.
(25-x)/4 = x
Multiply both sides by 4.
25-x = 4x
Add x on both sides.
25 = 5x
Divide both sides by 5.
5 = x
Hello friend,. I hope it's helps you
