Answer:
a^3 + b^3
Step-by-step explanation:
(a + b)(a^2-ab+b^2)
a(a^2 -ab +b^2) +b(a^2-ab+b^2)
a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3
a^3 -a^2b +a^2b ab^2-ab^2 + b^3
The final answer will then be:
a^3 + b^3
Hope this helps! Have a great one! And I give out the best of luck for whatever quiz this is on!
Answer:
<h2>x = - 20</h2>
Step-by-step explanation:

<u>Move 3x to the other side of the equation</u>

<u>Move -14 to the right side of the equation.</u>

Multiply both sides by - 1

We have the final answer as
<h3>x = - 20</h3>

Answer:
<h3>Defination of Quadrilateral Triangle :- </h3>
- A triangle is a simple closed curve or polygon which is created by three line-segments. On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
<h3>Examples of Quadrilateral Triangle :- </h3>
- A quadrilateral is a closed two-dimensional figure that has 4 sides, 4 angles, and 4 vertices.
- Examples of quadrilaterals are :- square, rectangle and trapezium.
Step-by-step explanation:
<h3>Hope this helps you dear ✌️</h3><h2>Carry on learning !! </h2>
The sum of the angles of a triangle is 180°.
The angles you know are 28° and 36°, so you can do this to find ∠B:
∠A + ∠B + ∠C = 180°
or 28° + ∠B + 36° = 180° Add 28 and 36
64° + ∠B = 180° Subtract 64 on both sides
∠B = 116
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
