Answer:
The answer to your question is letter C. 7y³ + 7n²y² - 22y²
Step-by-step explanation:
y²(4y + 7n² + 2) - 3y² (-y + 8)
Multiply
4y³ + 7n²y² + 2y² + 3y³ - 24y²
Use the associative property for like terms
(4y³ + 3y³) + (2y² - 24y²) + 7n²y²
Simplify like terms
7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²

Answer:
Triangle x = 30. Pentagon x = 50
Step-by-step explanation:
For the triangle,
Find the angle which is beside x in the triangle,
let's name that angle y, so 55 + 55 + y = 180 ( we find 55 by subtracting both angles 125 from 180)
110 + y = 180
Y = 180 - 110
y = 70
Now that we have find Y, we can easily find x by subtracting 70 from 180 which would be, 70 + X = 180
x = 180 - 70
x = 30
For the pentagon,
Again find the angle which is beside x in the pentagon,
let's name that y again, 90 + 120( by subtracting 60 from 180) + 110( by subtracting 70 from 180) + 90 + y = 540
210 + 200 + y = 540
410 + y = 540
y = 540 - 410
y = 130
Now that we have find y, we can easily find x by subtracting 130 from 180 which would be, 130 + x = 180
x = 180 - 130
x = 50
Hope this helps!
Answer:
Eric drove 28 7/11 miles with 1 gallon of gas.
Step-by-step explanation:
You just use long division and do 315 divided by 11, and you should get 28R7 so you just turn that R7 into 7/11.
Have a nice rest of your day :)
