Answer:
16 feet
Step-by-step explanation:
Area of a Triangle: (Base*Height)/2.
Therefore, Base:(2A)/Height =(2*24)/2=16
Answer:
x+y=2
Step-by-step explanation:
Standard Form: ax+by=c
For most convenience start with slope-intercept form: y=mx+b
1. -1 = -1(3)+b - solve for b
b=2
y= -1x+2 (slope-intercept form)
2. Now convert to standard form
Add 1x to both sides:
1x+y=2
