Answer:
x=-7 x=4
Step-by-step explanation:
(X-2)(x+5)=18
FOIL
x^2 +5x -2x-10 =18
Combine like terms
x^2 +3x -10 = 18
Subtract 18 from each side
x^2 +3x -10 -18 = 0
Combine like terms
x^2 +3x -28 =0
Factor
What two numbers multiply to -28 and add to 3
7*-4 = -28
7+-4 = 3
( x+7) ( x-4) =0
Using the zero product property
x+7 =0 x-4=0
x=-7 x=4
Step-by-step explanation:
The pizza chain has 5 different topings.
Number of different pizzas = 2⁵ = 32.
We have 2^n >= 1000.
Since 2⁹ = 512 and 2¹⁰ = 1024,
the minimum number of toppings is 10.
