Solve for x.

4x + 5 = 25

Answers

Answer 1
Answer:

The value of x of equation 4x + 5 = 25 is 5.

What is linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

Given,

4x + 5 = 25

First subtract 5 from both sides,

4x + 5-5 = 25-5

4x=20

Now divide both sides by 4,

x=5

Hence, the value of x of equation 4x + 5 = 25 is 5.

Simplify
2x2(4x3 - 3x2 + 6x).

Answers

Answer:

The simplified form of the provided expression is 8x^(5) - 6x^(4) + 12x^(3)

Step-by-step explanation:

Consider the provided expression.

2x^2(4x^3 - 3x^2 + 6x)

Use the distributive property:

a(b+c)=ab+ac

By using the above property we can simplify it as shown:

2x^2(4x^3 - 3x^2 + 6x)

8x^((2+3)) - 6x^((2+2)) + 12x^((2+1))

8x^(5) - 6x^(4) + 12x^(3)

Thus, the simplified form of the provided expression is 8x^(5) - 6x^(4) + 12x^(3)

You have to simplify this without any negative exponents. Where would I start?

Answers

You  have these: (a^m)^n = a^(m*n) and a^(-n) = 1/ (a^n), with n > 0  => (81^5 * y)/(x^5);
