Answer:
A
Step-by-step explanation:
At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1) part. This happens for x=1. So you can already rule out answers C and D.
Now fill in x=-2 in both remaining answers and see what happens.
For A: y = -2(-2 - 1)² + 3 = -15
For B: y = (-2 - 1)² + 3 = 12
That eliminates B and leaves A.
13+2(5c-2)=29
(2*5c) and (2*-2)
13+10c-4=29
add 4
13+10c= 33
subtract 13
10c=20
divide by 10
c=2
Answer:
15) diagonals are congruent in rectangles and squares; looks like a square
16) SW = 31
Step-by-step explanation:
since diagonals are congruent in rectangles then 'a+30' equals '2a+29'
a + 30 = 2a + 29
30 = a + 29
a = 1
SW = WU = TW = WV
Probably a plane unless there's more to the question
