You have the length of the sides? If not: a and b is the length of the scratch, h is the height <span>This lateral surface area = 2ah+2bh=2h(a+b)</span>
35+25=60
y=60
If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.
To get your answer you first subtract 10 from 128 which is 118.
Answer:
4x(3x^2-x+5)
Step-by-step explanation:
12x^3-4x^2+20x
=4x(3x^2-x+5)
