The solution set: {0, -11} .
____________________
Given: -p² − 11p = 0 ;
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "negative" value ;
-1 * { -p² − 11p = 0 } ;
to get:
p² + 11p = 0 ;
On the "left-hand side" of the equation, factor out a "p" ;
p(p + 11) = 0 ;
p = 0 ;
p = -11 .

15 and a half (15.5) quarts
Get each in common units
Orange 2 gallons X 4 quart per gallon = 8 quarts
Pineapple 4 quarts no change
Cranberry 3 pints / 2 pints per quart = 1.5 quarts
Apple 8 cups / 4 cups per quart = 2 quarts
Add them all together 8+4+1.5+2=15.5
Answer:
5
Step-by-step explanation:
Let's work from the middle of the equation to the outside of it. Our first part of the equation is 3+4, which equals seven, so we have the equation:
81-2[5(7)]
Then, we multiply 5 and 7, which is 35, so we get the equation:
81-2[35]
Then we have -2 outside of the brackets, so we can multiply -2 and 35, which is -75, so we have the equation:
81-75
Which is 5.
