Twenty is 40% of 50 because 10% of 50 is 5 so 5*4 = 20
Is the x2 supposed to be squared?
471-368=103
103/2=51.5
368+51.5=419.5
The number between 368 and 471 is 419.5
The answer is 2/3
although many answers may work
Answer:
x² + 5x + 6
Step-by-step explanation:
Foil means first, outside, inside, last
First: (x+2)(x+3)
x × x = x²
Inside: (x+2)(x+3)
x × 3 = 3x
Ouside: (x+2)(x+3)
2 × x = 2x
Last: (x+2)(x+3)
2 × 3 = 6
adding them together:
x² + 3x + 2x + 6 = x² + 5x + 6
