Answer:

Perimeter of Triangle: 6x+15

x=12.5

Step-by-step explanation:

The perimeter is the sum of all of the sides of the triangle.

Hence, the perimeter =3x+3x+15=6x+15

Since the perimeter is 90, 6x+15=90.

Subtract 15 from both sides:

6x+15-15=90-15

6x=75

Divide both sides by 6:

\frac{6x}{6}=\frac{75}{6}

x=12.5

What’s the equation when the line is (6,5) and slope is 2/3
Vsevolod [243]

Answer:

y=2/3x+1

Step-by-step explanation:

using the slope intercept formula, y=mx+b, where m is the slope, and b is the y intercept. So we get the equation y=2/3x+b, because the slope is given, then you use the given point and substitute it into the equation, 5=2/3(6)+b which you can solve and you will get 5=4+b, b =1, then you add 1 to your original equation to get your answer, y=2/3x+1
