Question

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

x + 4
x + 40
3x + 13
3x + 43
he expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24?

y – 20
y – 14
y – 8
y – 6
What is the quotient?

x + 1)3x2 − 2x + 7

3x − 5 +
3x − 5 +
3x + 5 +
3x + 5 +

Answer 1

1) Side length = (12x + 52)/4 = 3x + 13.

2) y^2 − 10y + 24 = (y − 4)(y − 6), so the other factor is y − 6.

3) (3x^2 − 2x + 7) ÷ (x + 1) gives quotient 3x − 5 with remainder 12, so as an expression: 3x − 5 + 12/(x + 1).
