How do you find the sum of cube ?
SIZIF [17.4K]

Answer:

(2x+5)(4x^{2} -10x+25)=0

Step-by-step explanation:

Given:

The given equation is.

8x^{3} +125=0

Find the some of cube.

Solution:

8x^{3} +125=0

2^{3}x^{3} +5^{3}=0

(2x)^{3} +5^{3}=0----------(1)

The sum of the cube formula is given below.

(a^{3} +b^{3})=(a+b)(a^{2} -ab+b^{2} )-----------(2)

By comparing equation 1 and equation 2

a=2x, b=5

substitute a and b value in equation 2

((2x)^{3} +5^{3})=(2x+5)((2x)^{2} -(2x)(5)+5^{2})

((2x)^{3} +5^{3})=(2x+5)(4x^{2} -(10x)+25)

((2x)^{3} +5^{3})=(2x+5)(4x^{2} -10x+25)

Therefore the sum of the cube (2x+5)(4x^{2} -10x+25)=0

AVprozaik [17]

Answer:

C

Step-by-step explanation:

The vertical line test is basically just drawing a vertical line and seeing if the line intersects the graph more than once. If it does, then it is not a function, if it doesn't than it is a function.

An angle measures 8.8° more than the measure of its complementary angle. What is the measure of each angle?
Fittoniya [83]

Based on the definition of complementary angles, the two angles are: 49.4° and 40.6°.

<h3>What are Complementary Angles?</h3>

Angles that are complementary angles have a sum of 90 degrees.

Let the angle be represented as x

Complement of the angle = (90 - x)

Therefore, we would have:

x = (90 - x) + 8.8

x = 90 - x + 8.8

x = 98.8 - x

x + x = 98.8

2x = 98.8

x = 98.8/2

x = 49.4°

The second angle would be: 90 - 49.4 = 40.6°

The angles are 49.4° and 40.6°.
