Answer:
see below
Step-by-step explanation:
5/8+ 3/8
Since the denominator is the same, we can add the numerators
(5+3) /8 = 8/8 = 1
5/8- 3/8
Since the denominator is the same, we can subtract the numerators
(5-3) /8 = 2/8 = 1/4
Given:
The equation of line is
.
A line is parallel to given equation and passes through the point (-4,-8).
To find:
The equation of parallel line.
Solution:
The equation of a line is

On comparing this equation with
, we get

So, slope of given line is -3.
We know that, slopes of parallel lines are equal. It means, the slope of the parallel line is also -3.
The parallel line passes through (-4,-8) and having slope -3. So, the equation of line is






Therefore, the equation of parallel line is
.
Answer:
(4x+5) (16x^2- 20x +25)
Step-by-step explanation:
Since both terms are perfect cubes, factor using the sum of cubes formula.
Cubes Formula:
a^3+b^3=(a+b)(a^2−ab+b^2)
where a=4x and b=5.
hence, why the answer is (4x+5) (16x^2- 20x +25)
