I'm having trouble on ixl here is what i have to do
factor 54r–42
write your answer as a product with a whole number greater than 1.

this is 7th grade algebra

6(9r-7)

Step-by-step explanation:

54r–42

Both 54 and 43 can be divided by 6

54/6 =9  and 42/6 =7

6*9r - 6*7

Factor out the 6

6(9r-7)

6(9r - 7)

Step-by-step explanation:

Think:  what's the largest factor shared by 54 and 42?

54 = 6·9 and 42 = 6·7

That largest common factor is 6.

Then 54r - 42 = 6(9r - 7)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
