An image of a rectangular prism is Show below: Part A: A cross section of the prism is cut with a plane parallel to the base. What is the name of the shape created by the crossover section ? Explain your aswer. Part B: If a cross section of the prism is cut diagonal to the base, what would be the shape of the resulting cross section? Explain your awnser.

step-by-step explanation:

it have the same area.brainliest

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
