The area of a rectangular school yard is given by the equation x2 + 19x + 90 as measured in square yards. the teacher wants you to run the length. how far will you run if x = 30?

-4 or -15

Step-by-step explanation:

Let's solve your equation step-by-step.

x^2+19x+90=30

Step 1: Subtract 30 from both sides.

x^2+19x+90−30=30−30

x^2+19x+60=0

Step 2: Factor left side of equation.

(x+4)(x+15)=0

Step 3: Set factors equal to 0.

x+4=0 or x+15=0

x=−4 or x=−15

x=−4 or x=−15

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
