Answer:
64,26
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
The box means its is a 90 degree angle
90 + 2x+ x-6 = 180
Combine like terms
84+3x = 180
Subtract 84 from each side
84+3x-84 = 180-84
3x=96
Divide by 3
3x/3 = 96/3
x = 32
The top angle is
2x = 2*32 = 64
The bottom right angle is x-6
32-6 = 26
Answer:
(0,4)
(1/2,7)
(2.25,7)
(3,4)
Step-by-step explanation:
you want to take each point and subtract five from the 'x' value and add two to the 'y' value
(5,2) → (5-5, 2+2) → (0,4)
(5.5,5) → (5.5-5, 5+2) → (0.5,7)
(7.25,5) → (7.25-5, 5+2) → (2.25,7)
(8,2) → (8-5, 2+2) → (3,4)

Answer:
3ab+2cb,2ca+2ab+2bc
Step-by-step explanation:
1. Collect like terms.
3ab+2cb,((3ca-ca)+(-ab+3ab)+2bc)
3ab+2cb,((3ca−ca)+(−ab+3ab)+2bc)
2. Simplify (3ca-ca)+(-ab+3ab)+2bc(3ca−ca)+(−ab+3ab)+2bc to 2ca+2ab+2bc2ca+2ab+2bc.
3ab+2cb,2ca+2ab+2bc
3ab+2cb,2ca+2ab+2bc
