Answer:
b) 7×8
c) 4×14
d) 2×28
Step-by-step explanation:
A factor pair of a number is a pair of numbers that, when multiplied will result in the given number.
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, and 56.
The factor pairs are:
Out of the options, only Option A is not a factor pair.
Range: 16 (20 - 4)
Median: 9 (average 8 and 10)
Mean: 9.5 (average all the numbers)
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
