Answer:
B. 4x+y=12
Step-by-step explanation:
You can either graph them or solve each one for x then identify the one with an equal slope and y-intercept of 12.
(x-2)(x-2)+6(x-2)+9
so first we distribute
x^2-2x-2x+4+6x-12+9
group like terms
x^2+2x+1
factor
find what 2 numbers add to get 2 and multiply to get 1
the numbers are 1 and 1
(x+1)(x+1)
Answer:
75
Step-by-step explanation:
All of the angles within the triangle must add up to 180 degrees. So, angle 2 =50
The angles 4,2,5 also equal 180 because they are on the blue line. Since angle 2=50 and angle 5= 55 angle 4 must be 75 which is needed to add up to 180.
