Answer:

y = (x + 5)(x - 4)

Step-by-step explanation:

Given

y = x² + x - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and 5 - 4 = + 1, thus

x² + x - 20 = (x + 5)(x - 4)

Answer:

Option 1: 2x + 11 = 90.

x = 79/2 or 39.5 degrees

Step-by-step explanation:

Option 1: You know that the angle for option one is 90 degrees because of the marking. Since you know that part of the angle is 11 degrees, you can set up an equation for 2x + 11 which equals to 90 degrees.
