Answer:

39 units by 51 units

Step-by-step explanation:

The painting is a scale factor of 1/3, so each side length is 1/3 of the original. To find the original multiply both side lengths by 3.

13x3 = 39

17 x 3 = 51

What does combining like terms refers to?

wolverine [178]

Combining like terms refers to adding all of the terms that have a exponent or a variable in an expression.

Example: 6y + 10y - 2

You would combine the like terms, which two numbers have a variable.

6y + 10y = 16y

After combing the like terms, the new expression should be:

16y - 2

Ashirt button has a diameter of 0.61 cm. Which of these is an approximate measurement of the circumference of the button?

Aleonysh [2.5K]

Answer:

1.92cm

Step-by-step explanation:

Circumference of a circle is computed using the formula:

$C=2\pi r$

Where:

r = radius

π = 3.14

Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.

We can then use the diameter to solve for the circumference by using the formula"

$C = \pi d$
