Answer:
1. Gcf = 9
2. Gcf = 1
3. Gcf = 2
4. Gcf = 30
5. Gcf = 5
6. Gcf = 2
7. Gcf = 25
8. Gcf = 12
9. Gcf = 100
Step-by-step explanation:
I think, I don’t know the other one.
To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.
(71+x)/2=78
71+x=156
x=85

Hello!
PERIMETER:
To find the perimeter of the trapezoid, simply add all sides together.
15 + 5 + 9 + 5 = 34
The perimeter is 
____________________________________________________________
AREA:
A =
h(
+
)
A =
4(9 + 15)
A =
4(24)
A = 2(24)
A = 48
The area of the trapezoid is 
Answer:
It doesn't intersect at that point
