Answer:

Factoring

Step-by-step explanation:

(x+4)² = 15

x² + 8x + 16 = 15

x² + 8x + 1 = 0

x =  \frac{ - 8 +  \sqrt{64 - 4} }{2}  =  - 4 +  \sqrt{15}  \\  \\ x =  \frac{ - 8 -  \sqrt{64 - 4} }{2}  =  - 4 -  \sqrt{15}

I hope this helps you :)

KIM [24]

An algebraic expression that represent how much Mr. Green paid in all is 3(m + 1) + d

<h3 /><h3>Pet fish</h3>

The following represents the items bought

  • Each bag has m mollies and 1 bala
  • He bought 3 of these bags

The expression that represents the items in a bag is:

Bag=m + 1\\

He bought 3 bags.

So, the total spent on pet fish is:

Total =3(m + 1)

<h3>Fish food</h3>

A box costs d dollars.

This means that, the total amount Mr Green spent in the store is:

Total =3(m + 1) + d
