Which shoes equivalent expressions?

the first option

Step-by-step explanation:

work with the first option:

a^2 + 3b -2a^2 = 3a^2 + 3b -4a^2

working with the left side:

simplify like terms: a^2 -2a^2 = -a^2

so, the left side is -a^2 + 3b

working with the right side:

simplify like terms: 3a^2 - 4a^2 = -a^2

so, the right side is -a^2 + 3b

set those equal to each other

-a^2 + 3b = -a^2 + 3b

they equal each other, so the first answer is correct.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
