3x+1. I need to find and write an equation for x
Alchen [17]

Answer:

x =\frac{-1}{3}

Step-by-step explanation:

As the given algebraic expression is

3x+1

In order to solve the expression 3x+1 for x, we have to

3x+1=0

Step 1: Subtract 1 from both sides

3x+1-1=0-1

3x=-1

Step 2: Divide both sides by 3.

\frac{3x}{3} =\frac{-1}{3}

x =\frac{-1}{3}

Therefore, x =\frac{-1}{3}

This is a congruent triangle. If we use Pythagorean theorm, we can see that 3^2+y^2=25

y^2= 16

y=4

(y is the base of the small triangle)

and since the big triangle and the small triangle are congruent(the ratios are the same), 3 is half of 6, and so the base of the small triangle is half of the big triangle's.

4*2=8

x=8
