Answer:

i thought it was 132 m2

Step-by-step explanation:

bc for each of the lateral faces are 24 (since 8 * 6 equals 48 and you divide it by 2) and there are 4 lateral faces so 24*4=96+36=132

area of all the lateral faces=96

area of base=36

96+36=132

Not sure. Please explain the steps.

Answer:

answer C

Step-by-step explanation:

hello

because this is not allowed to divide by 0 I would take x real different from 0 and from -5/4

$\dfrac{8x^3-10x^2-25x}{4x^2+5x}=\dfrac{x(8x^2-10x-25)}{x(4x+5)}=\\\dfrac{8x^2-10x-25}{4x+5}=\dfrac{(4x+5)(2x-5)}{4x+5}=2x-5$

indeed if we develop

$(4x+5)(2x-5)=8x^2-20x+10x-25=8x^2-10x-25$

hope this helps
