Add 1 to both sides

8x^3 = 1

Divide both sides by 8

x^3 = 1/8

Take the cube root of both sides

x = 1/3√8

Use the Division Distributive Property: (x/y)^a = x^a/y^a

x = 1/3√8

Calculate

<u>x = 1/2</u>

astra-53 [7]

Answer:

4x^6+12x^5+8x^4

Step-by-step explanation:

To find the area of a triangle, you need to multiply the width by the height. In this case:

(4x^3)(x^3+3x^2+2x)=\\4x^6+12x^5+8x^4

a right triangle has a hypotenuse with a length of 20. the lengths of the legs are whole numbers. what are the lengths of the le
Y_Kistochka [10]

Answer:

12;16

Step-by-step explanation:

The Pythagorean theorem states that

a^2+b^2=c^2 where a and b are legs of a triangle, and c is the hypotenuse.

This means that we have to find 2 values that once squared, add up to 400. (20^2)

Based on this, we can use the values of 12 and 16 to satisfy this.

12^2+16^2=144*256=400

Therefore, the legs of the triangle are 12 and 16.
