Because a rectangular pyramid's base is square, the cross section would be as well
B-8 would be the answer. This is because we are saying you have 8 less than something. So no matter what something is, we are taking away 8 from it. Since our something is unknown, we use our variable 'b' in its place, and subtract 8, giving us b-8.<span />
Answer:
Option D.
Step-by-step explanation:
Let the coordinates of a point which divides the segment XY in the ratio of m : n is (x, y).
Segment X(-4, -9) and Y(4, 7) has been divided in the ratio of 2 : 6.
Therefore, x =
= -
= -2
and y =
=
= -5
Therefore, the point (x, y) is (-2, -5).
Option D. will be the answer.
Answer:
<em>-3x+10y</em>
Step-by-step explanation:
Given the expression , we are to simplify by combining the like terms. On simplification we have;
Open the parenthesis:
Collect the like terms:
Sum up the resulting expression
<em>Hence the required expression on simplification is -3x+10y</em>

D) 160
Step by step explanation
To find the area of a object you must multiply the length by the height in this case they gave you an equation instead of an exact height so the first thing you have to do is:
20m x 16m = 320m
But as you can see, all of the answers have an exponent of two meaning we would have to divide 320 by 2
320 ÷ 2 = 160
