Answer:

Step-by-step explanation:
First we need to rewrite 3x-5y=8 in slope-intercept form.

The slope of this line is

The line perpendicular to this line will have a slope that is the negative reciprocal of 3/5, which is

This line passes through (3,7).
The equation is given by:

We substitute the point and slope to get:

We multiply through by 3 to get:

Expand to obtain:



Answer:
Isosceles
Step-by-step explanation:
triangle-a triangle with at least 2 congruent sides
150-4[3+9/4-1*(14-11)^2]
150-4[12/3*(3)^2]
150-4[4*3^2]
150-4[4*9]
150-4*36
150-144
6
(I think)
The third one
3(x+5) = 3 * x + 3 * 5
