P²-12p-49=-103
add 49 to both sides
p²-12p=-54
take 1/2 of the linear coefient and square it
-12 is the linear coefitnt so -12/2=-6, (-6)²=36

add 36 to both sides
p²-12p+36=-18
factor perfect square trinomial
(p-6)²=-18
square root both sides
no solution because we can't squaer anything and get a negative

The goal of a Toy Drive is to donate more than 1000 toys. The Toy Drive already has collected 300
maksim [4K]

Answer:

t > 700

Step-by-step explanation:

1000 - 300 = 700

This means they still need at least 700 toys to go.

In the question it says "donate more" so we are going to use the ">" symbol.

Let "t" equal the number of toys they need to donate.

t > 700

Best of Luck!
