Given: w²+9=6w [0, 3, 6, 9]

We need to substitute each number for w and find which works

Sub Zero: 0²+9=6×0

Simplify: 9=0. 9 does not equal 0, so it is not 0

Sub Three: 3²+9=6×3

Simplify: 9+9=18

Addition: 18=18

The statement 18=18 is true, therefore we have our answer.

Answer: The second option is correct. 3 would be the correct number to substitute to make the equation correct.

PilotLPTM [1.2K]

I’m assuming “triple 4” is just 3 times 4.
Using the information from the problem, we can form an equation that reads,
3*4 + 7*7

Solve:
12 + 49 = 61

The answer is 61

Which pair of angles are adjacent angles?

Sloan [31]

Your answer is B. 1 and 3.
This is because adjacent angles are angles that could form one angle if the line inbetween them was removed, which means they have a common side. Angles 1 and 3 are the only angles out of the options that have a common side, so they must be the answer.

I hope this helps!

Cecilia made an envelope to mail a letter. She colored the regular trapezoid flap on the bottom of the envelope blue, as shown.

podryga [215]

Answer:

The correct option is:

14 inches

Step-by-step explanation:

The question is incomplete because the picture of the flap is not shown in the question nor the measurements are given. First lets complete the question. The figure was this question is attached below.

We can see that the bottom width of the trapezoid is 9 inches, the top width of the trapezoid is 5 inches, and it has a height of 2 inches.

The area of trapezoid is given as:

Area = ((Top width + Bottom width)/2) · h

Area = ((9+5)/2) · 2

Area = (14/2) · 2

Area = 7 · 2

Area = 14 inch²
