What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) 7x2 + 5x 7x2 + 11x 11x2 + 5x 11x2 + 11x

(A)

Step-by-step explanation:

Given:The given expression is:

To find: The difference of the two polynomials.

Solution: The given expression is:

Upon solving the above equation, we get

Combining the like terms and then solving,

which is the required difference.

Hence, option A is correct.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

ratio is 2 : 9

the answer is three

13.5 : 3
