Question 2

How can you describe the solution set of the equation 16x2 - 8x + 1 = 0?

Revolt · Accepted Answer

There is one real solution because the expression’s factors are the same.

Question 3

Using the zero product property, the equation is (w - 10)(w - 6) = 0(w - 10)(w + 6) = 0✔ (w + 10)(w - 6) = 0(w + 10)(w + 6) = 0.

Revolt · Accepted Answer

✔ (w + 10)(w - 6) = 0

Question 4

What is the length of the rectangle? ⇒ 10 yards

Revolt · Accepted Answer

10

Question 5

Which equation represents the situation? ✔ w(4 +w) = 60w + 4 + w = 60X 2w + 2(4 + w) = 60

Revolt · Accepted Answer

✔ w(4 +w) = 60
