<span>Three numbers can be defined as x, y, and z.
x + y + z = 64
y = x+3
z = 2x - 11
.
substitute for y and z
x + (x+3) + (2x-11) = 64
4x -8 = 64
4x = 72
x = 18
.
y = x+3 = 21
z = 2x -11 = 2(18) -11 = 36-11 = 25
.
x + y + z = 18 + 21 + 25 = 64
Correct.

Answer: The three numbers are 18, 21, and 25.</span>
13. 9x^2-36x+36
14. 4x^2+14x+20
Remember area formula for a square is Length times Width.
The area formula for a triangle is 1/2base times height.
Answer:
A=75
B=60
C=45
Step-by-step explanation:
5+4+3=12
every triangle is equal to 180 so we divide
180/12=15
then we multiply each angle by 15
5*15
4*15
and 3*15
don't forget to check your work by adding the answers together to get 180
