Answer:
2x+9y=18
Step-by-step explanation:
Distribute the denominator
y=-2/9x+2
9y=-2x+2
9y+2x=2
im sorry if this is wrong
Answer:
Cube 1: 3375 cubed inches, 1350 inches squared.
Cube 2: 512 cubed inches, 384 inches squared.
Step-by-step explanation:
Formula for Volume of a Cube:
(s - side length)
Formula for Surface Area of a Cube:
(s- side length)
<h3>For Cube 1:</h3>
The side length's 15 inches.
Find the volume:

The volume of cube one is 3375in³.
Find the surface area:

The surface area of cube 1 is 1350in².
<h3>For Cube 2:</h3>
The side length's 8 inches.
Find the volume:

The volume of cube two is 512in³.
Find the surface area:

The surface area of cube 2 is 384in².

Question 1:This is a 45-45-90 right triangle. If the leg length is

, then the hypotenuse length will be

.
The leg length of this 45-45-90 right triangle is 8. Multiply that with the square root of 2. You get

. Thus, the last choice is your answer.
Question 2:This triangle can be identified as a 30-60-90 right triangle.
Let's say the smallest leg as a length of

.
Then, the longer leg will have a length of

.
Also, the hypotenuse will have a length of

This triangle follows this format, making it a 30-60-90 right triangle. Thus, the angles are 30, 60, and 90.
Hope this helps! :)
