Answer:
6 + 12² = x
There's not an explanation for this-
For a rectangle, it will have to be 3 cubes by 6 cubes or 6 cubes by 3 cubes.

First find the equation of the given line. Let y=mx+b. 1=4m+b;-3=-4m+b. Solving, and get b=-1, m=1/2. So the line that is perpendicular to it must have slope -1/m=-2. Suppose the form is y=-2x+b, since it passes through (-4,3), the point slope form is y-3=-2(x+4).
Given that the recursive formula is:
an=an-1+7
first term is
a1=17
the second term will be:
a2=a(2-1)+7
a2=a1+7
a2=17+7
a2=24
To evaluate for the explicit formula we use the formula:
an=a+d(n-1)
where
a=first term
d=common difference
from the calculations above:
d=24-17=7
thus the explicit formula will be:
an=17+7(n-1)
an=17+7n-7
an=7n+17-7
an=7n+10
Answer: B] an=7n+10
