Do you have answer choices ?
Answer:
=(a-b)(a^2+ab+b^2)
= a^3+a^2b+ab+ab^2-ba^2-ab^2-b^3
SIMPLIFY
=a^3+ab-b^3
Answer:
7/8
Step-by-step explanation:
In order to solve this problem, we need to find a common denominator, which is basically the least common multiple of the two denominators.
The two denominators are 8 and 4, and their LCM is 8. So, let's convert all these fractions so that their denominators are 8.
3/8 is already there, so we don't need to touch that.
To make 2/4 have a denominator of 8, we need to multiply the numerator and denominator by 2: (2 * 2)/(4 * 2) = 4/8
Now, we add: (3/8) + (4/8) = 7/8
That's why the answer is 7/8.
Hope this helps!

Step-by-step explanation:
If ∠ D ≡ ∠ CED then CD ≡ CE
The base angles theorem states that if the sides of a triangle are congruent, that is isosceles triangle the the angles opposite these sides, the base angles, are equal.
Here we are using the converse of base angle theorem (b)
That is if 2 angles are congruent ( base angles ) then the sides opposite these angles are congruent.
