20) -5(1 - 5x) +5(-8x - 2) = -4x – 8x
Alchen [17]

Answer:

x = -5

Step-by-step explanation:

-5(1 - 5x) +5(-8x - 2) = -4x – 8x

First lets simplify each side of the equation.

-5+25x-40x-10 = -4x-8x

Combine like terms

-15x-15=-12x

Add 15x to both sides (addition property of equality)

-15=3x

Divide each side by 3 (division property of equality)

x=-5

The answer is x = -5

Expand x(x – 4)<br> Please answer!!! I will mark you as brainliest if you answer and its right!!
Mekhanik [1.2K]

The expression x( x - 4 ) when expanded is x² - 4x

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.

When a bracket is expanded, each term is multiplied by the expression outside of the bracket.

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.

Consider the expression,

x( x - 4 )

Let us assume y = x( x - 4 )

Using the distributive property, a( b + c ) = ab + ac

y = x( x - 4 )

y = x · x - x · 4

y = x² - 4x

Therefore, x( x - 4 ) = x² - 4x

Therefore, the expression when expanded is x² - 4x.
