2×5=10
3×4=12
10+10+12+12=44 inches
you add 10 and 12 twice because you have to account for the top and bottom of the piece of wrapping paper as well as the left and right sides of it

Answer: the perimeter of the wrapping paper Katie cut was 44in².

explanation: if the box's length is 5in., that means you to multiply by 2 because she cut it 2x as much as the length as the box, if the box's width was 4in., then you have to multiply by 3 since she cut it 3x as much of the width as the box itself.

Now, you have to add both products to get your perimeter:

equation: (5×2) + (4×3) = 44

victus00 [196]
SO YOU HAVE X(-14X+9). ALL YOU DO IS THE DISTRIBUTION PROPERY OR MULIPLE BY X

SO WE GET -14X^2+9X.

X(-14X+9)= -14X(*)X+9(*)X= -14X^2+9X

Complete these ordered pairs for this equation. (0, ), (-2, ), (4, ) y=2x
quester [9]

Answer:

Part 1) The ordered pair is (0,0)

Part 2) The ordered pair is (-2,-4)

Part 3) The ordered pair is (4,8)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a direct variation

y=2x

Complete the ordered pairs

Part 1) we have (0,?)

For x=0

Substitute in the equation and solve for y

y=2(0)=0

therefore

The ordered pair is (0,0)

Part 2) we have (-2,?)

For x=-2

Substitute in the equation and solve for y

y=2(-2)=-4

therefore

The ordered pair is (-2,-4)

Part 3) we have (4,?)

For x=4

Substitute in the equation and solve for y

y=2(4)=8

therefore

The ordered pair is (4,8)
