Just distribute the 3. 3(x + 4y) = 3x + 12y
3x + 12y is the answer.
The height is 5.
Since V=Base*height, I just divided the volume by the base.
175/35
=5
So the height would be 5. You can check to see if it's true by multiplying 35*5, which gives you 175.
Answer
290 degrees
Step-by-step explanation:
A circle is always 360 degrees, m<ABC+m<ADC=360
substitute the angles and your equation should be 70+x=360
Bring 70 to the other side,
360-70= 290
x=290
*make sure to put the degrees symbol or it would you mark you incorrect.*
C i don’t have a reason it’s just right
79
x^2 + y^2 + 5xy = (x+y)^2 + 3xy = 7^2 + 30 = 79
