What is the answer to this question? Please
AnnZ [28]

Answer:

y² + 8y + 16

Step-by-step explanation:

Given

(y + 4)²

= (y + 4)(y + 4)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

y(y + 4) + 4(y + 4) ← distribute both parenthesis

= y² + 4y + 4y + 16 ← collect like terms

= y² + 8y + 16

For what values of y:s the value of the fraction 4.5−2y/5 less than the value of the fraction 2−3y/10 ?
Andre45 [30]

Answer:

  7 < y

Step-by-step explanation:

The relation you're interested in is ...

  (4.5 -2y)/5 < (2 -3y)/10

  9 -4y < 2 -3y . . . . . . . . . multiply by 10

  7 < y . . . . . . . . . . . . . . . .  add 4y-2

The value of the first fraction will be less than that of the second fraction for values of y greater than 7.
