Which figures will have a volume that is greater than 100 cubic units? Select two options. a rectangular prism with dimensions of 4 by 5 by 4 a rectangular prism with dimensions of 2 by 12 by 6 a rectangular prism with dimensions of 1.5 by 8 by 8 a triangular prism that is 6 long and has a triangular face with a base of 4 and a height of 12 a cube with side length 4.

Calculations for a rectangular prism: 1. Given the length, width and height find the volume, surface area and diagonal of a rectangular prism. h, l and w are known; find V, S and d. V = lwh. S = 2(lw + lh + wh)

Options-2

Option-4

Step-by-step explanation:

two options have Volume greater than 100 units³

remember the formula of Volume of rectangular prism

given that,

thus substitute:

simplify multiplication:

since 144>100 it's one of our answer

remember the formula of triangular prism

given:

Thus substitute:

simplify multiplication:

since 144>100 it's our answer

the other options don't satisfy the condition

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
