Answer:
5(x+4)(x+8)
Step-by-step explanation:
5x^2+60x+160
factor out the 5 first,
5(x^2+12x+32),
then factor out the trinomial,
find 2 numbers that when they multiply,
you get the third term, which is 32 in this case,
and when they add up,
you get the second term, which is 12 in this case.
5(x+4)(x+8)
This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3

Answer:
4. A rectangle is a square
Step-by-step explanation:
A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.
