Answer:
y = 4x - 1
Step-by-step explanation:
To write the equation of a line using the slope and a point, use the point slope form 
.
Substitute m = 4 and (3,11).
y - 11 = 4 ( x- 3)
y - 11 = 4x - 12
y = 4x - 1
The answer would be 27. If ABC is 3 times the length of AB then it would be the same for AC.
Answer:
93
Step-by-step explanation:
Add 36 to both sides of the equation:

0 + ___ = 93
___ = 93
The integer 93 goes in the blank.
Answer:
81 is the scale of drawing.
Step-by-step explanation:
Area of the house in drawing = A =
Let the factor by which scaling is present in the drawing be s.
Area of the house in reality = A' =
1.Simplify.
-2{x}^{2}-4x+13+12{x}^{2}+2x-25−2x2−4x+13+12x2+2x−25
2.Collect like terms.
(-2{x}^{2}+12{x}^{2})+(-4x+2x)+(13-25)(−2x2+12x2)+(−4x+2x)+(13−25)
3.Simplify.
