y=3x+6
Step-by-step explanation:
point 1 (2;12)
point 2 (4;18)



m=3
y=mx+b
sub in a point and gradient
12=3(2)+b
12=6+b
b=6
y=3x+6
Using proportions, the value of x that makes the triangle similar is of x = 14.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we want the triangles to be similar, hence the lengths of it's sides follow the proportion given next:

Applying cross multiplication:
6x = 12 x 7
x = 2 x 7
x = 14.
The value of x that makes the triangle similar is of x = 14.

Answer:
c=93
Step-by-step explanation:
35+3(x+2)+52=180
87+3(x+2)=180
87+3x+6=180
93+3x=180
3x=180-93
3x=87
x=87/3
x=29
3(29+2)
3(31)=93
-28-(-24)=-4
14-18=-4
28-32=-4
Any of these should work and there are plenty more that would work as well
