- (3x^)(-2x*) = 3(-2)x+4 = 6x*
i don’t know how to simplify this, what would it be simplfied?

i think it would be 42cm

i think the correct option is the second option.

i think its a and d

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
