Identify the pair of expressions in which all terms are like terms. a) (2x2 + 3y), (y + 2x - 4) b) (2x2 + 3y), (5y + 3x2 )

c) (x3 – y + 3), (5y + 3x2 ) d) (y + 2x - 4), (x3 – y + 3)

pls explain

Step-by-step explanation:

a) (2x2+3y)+(y+2x-4)

(4+3y)+(y+2x-4)

4+3y+y+2x-4 this mean negative times positive is negative

4-4+3y+y+2x

0+4y+2x

4y+2x

I think this is the answer but I am not sure

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math
