I’m pretty sure
8. would be false because BK would be 12 where as DF is 10.8
9. is true
Answer:

Step-by-step explanation:
The standard form of this equation is

m stands for the gradient or the slope, and c represents the y-intercept

A is the correct answer
Or
Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -5
When you have a function of g(-1) you first plug in -1 to all x's then you solve it.
Answer: x=0
Answer:
54, 36
Step-by-step explanation:
67+59+x=60*3
126+x=180
x=54
