Answer:
36
Step-by-step explanation:
EF = is 1/3 of 15
Since the triangles are similar, then the perimeters are similar.
The perimeter of EDF is 12
The perimeter of ABC should be 3 times as large.
3*12 = 36
The perimeter of ABC = 36
Answer:
40 degrees!
Step-by-step explanation:
95 + 45 = 140
180 - 140 = 40
She must have multiplied it by 5.
That would've given her:
x - y = 15
2.5x + y = 25
Now we can add them and the y-terms will eliminate each other. Because one is -y, and the other is positive y. -y + y = 0.
Answer: d) 14
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d):

Equation of a line passing through (2, 18) and (–3, 8):

Comparing resulting equation
to
, we get value of b= 14.
Hence, correct option is d) 14
