Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)
3x^2y^2 − xy^2 − 2y^2
y^2 ( 3x^2 - x -2 )
y^2 (3x+2)( x - 1)
Part B: Factor x^2 + 6x + 9. Show your work. (3 points)
x^2 + 6x + 9
= x^2 + 2*3x + 3^2
= (x+3)(x+3)
= (x+3)^2
Part C: Factor x2 − 25. Show your work. (3 points)
x^2 - 5^2

Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
Answer:
help with what??
Step-by-step explanation:
Hello!
Since the angles are alternate interior angles they equal each other
5x - 28 = 3x + 12
Now you solve this algebraically
5x - 28 = 3x + 12
Subtract 3x from both sides
2x - 28 = 12
Add 28 to both sides
2x = 40
Divide both sides by 2
x = 20
Now we put x into the equation we are wanting to find out
5x - 28
5(20) - 28
Multiply
100 - 28
Subtract
72
The answers are x = 20 and 5x - 28 = 72°
Hope this helps!
