Reflect trapezoid ABCD over the y-axis. Then reflect this image over the x-axis.

step-by-step explanation:

f

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
