What is the answer 5(x-4)=3x+4
ruslelena [56]

Step-by-step explanation:

Simplify the left side:

5x - 20 = 3x + 4

Move all terms containing  x  to the left side of the equation:

2x - 20 = 4

Move all terms not containing  x  to the right side of the equation:

2x = 24

Divide each term by  2  and simplify:

x = 12

A rectangle has a length of (6x+1) units and a width of (3x+1 units. Express the area of the rectangle as trinomial. Please I re
dimulka [17.4K]

whenever you have say a multiplication of a binomial or any polynomial, you can simply multiply each term of one by the other's terms, namely

(a+b)*(c+d+e)  => a(c+d+e) + b(c+d+e), and then add like-terms.

\bf \stackrel{length}{(6x+1)}\stackrel{width}{(3x+1)}\implies 6x(3x+1)+1(3x+1)\implies (18x^2+6x)~~+~~(3x+1) \\\\\\ 18x^2+6x+3x+1\implies \stackrel{\textit{adding like-terms}}{18x^2+9x+1}

Look at the line graphed below. Write an equation of a different line that has the same y- Entercept as the line shown, but has
AlekseyPX

Supposing the line graphed is y = 2x + 3, the equation of the different line is:

y = 4x + 3.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem, the equation is:

y = 2x + 3

Hence, the slope is 2 and the y-intercept is 3. For the new line, we want to:

  • Double the slope, hence m = 4.
  • Keep the same y-intercept, hence b = 3.

Then, the equation of the different line is:

y = 4x + 3.
