Do you understand what I did here?
Answer:
-2(x^2 - x - 1).
Step-by-step explanation:
3x - 2x^2 - x + 2
= 2x - 2x^2 + 2
= -2(x^2 - x - 1)
The measure for angle z is 137°. Because angle 43° and angle z are equal to 180°. Which leads u to this equation.
Answer: 19 macaroons
Step-by-step explanation:
Let's create an equation to represent this situation. Let x represent the number of macaroons that Em made.
33=x+x+5
33=2x+5
33-5=2x+5-5
28=2x
28/2=2x/2
14=x
This means that Em made 14 macaroons.
14+5=19
Therefore, Jim baked 19 macaroons.
Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8
