Answer:

The length is 24.

Step-by-step explanation:

The equation for the perimeter of a rectangle is 2l+2w

Therefore, we have the equation

P=2l+2w

Next, we plug the values we know into the equation.

124=2l+2(38)

Next, we can simplify that

124=2l+76

Subtract 76 from both sides

48=2l

Divide both sides by 2.

l=24

What is the equation of the funcion that is graphed as line b?
dolphi86 [110]

Answer:

The equation for b would be y = 1/2x + 1

Step-by-step explanation:

In order to find this, start by finding two points on the line. We'll use (0,1) and (2, 2). From there we start by finding the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - 1)/(2 - 0)

m = 1/2

Now using that, we can plug it, along with a point into point-slope form to get the answer.

y - y1 = m(x - x1)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Building a model of an object "to scale" means that the height of the object is ____________ to the height of the model.
Zina [86]
The height of the object is EQUAL to the height of the model. We can see this in advertising when for example cereal is being advertised and on the box is says "actual size" because the cereal is drawn to scale.
