Area of trapezoid

A=h(b+B) divided by 2

* * * * *

where A = area

h = vertical height

b and B are the lengths of the parallel sides.

How do you find the equation of a graph

You find the equation of a graph by finding an equation with a graph.

Jack cut a piece of wood that was 8 feet long into two pieces one piece is three times as long as the other how long in the shorter piece of wood

Let x be the length measure of the shortest piece of wood, and 3x the length measure of the other piece of wood. So we have:

x + 3x = 8

4x = 8 divide by 4 to both sides;

x = 2

The length measure of the shortest piece of wood is 2.

Find three consecutive even integers that have the sum of 42.

They are 12, 14 and 16.

3a plus 5 equals 5a plus 3

If 3a+5=5a+3, then:

3a+5 - 3a = 5a+3 - 3a

5=2a+3

5 - 3=2a+3 - 3

2=2a

a=1

What is the image of point 3 and 5 if the rotation is 180 degrees

What is the image of point (3, 5) if the rotation is

How do you get the answer 7 using only numbers -4-3-2-1

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
