What is the formula for the perimeter of a rectangle

For a rectangle,

P = 2L + 2W (L is length, W is width)

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.

Rewrite the formula to solve for c

c=a-b

2a - 8 10 or 8a 4 68

all real numbers :)

What formula expresses newton's second law of motion

The formula of Newton's second law is F=ma, for force( F) equals the mass (m) times the acceleration (a).

Darren can get to work in 30 minutes The speed limit is 35 mph but there are three stop lights With the traffic and lights he can average 30 mph How far is he from work

(30 mph) x (1/2 h) = 15 miles

What is the width of the rectangle if the area is 132 square feet and the length is 12 feet

11 feet

7x-4x plus 2x plus 5 equals 2x plus 14

7x-4x+2x+5=2x+14

5x+5=2x+14

3x=9

x=3

If a train travels 200 miles in 2.5 hours what is the rate of speed

80 miles per hour. All you have to do is divide 200 by 2.5.

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

Calculate the distance a car would travel at 80 mph for 2.5 hours

The answer is 200

What are coordinates used on

Maps, and Graph Paper.

Does the graph of this line y-3x-5 have a negative slope or a positive slop

2

How long will it a train to travel 200 miles at the rate of 80 miles at the rate 80 miles per hour

two and a half hours, 200/80 = 2.5

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

Does y12x 1 have a negative or positive slope

If you mean: y = 12x+1 then it has a positive slope of 12 and a y intercept of 1

When the absolute value of the slope gets smaller the graph of a line gets what

When the slope of a line reaches zero it then will be parallel to the x or y axes depending if its a positive or a negative slope.
