Simplify the algebraic expression:

5 + 3(2y - 4) - 11y

5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1

− 7 + 6 − 1 1  −7+6y−11y − 7 − 5

− 7 − 5 −7−5y − 5 − 7

Solution: −5−7

-5y -7

Step-by-step explanation:

expand: 3(2y-4):   6y-12 = 5+6y-12-11y        

simplify: 5+6y -12-11y:      -5y-7

-5y-7

i could probably can you me with a question of mine?

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
