Answer:
x = -2
x = -10
Step-by-step explanation:
<u>Step 1 :</u><u> Rearrange</u>
x² + 12x + 20 = 0
<u>Step 2:</u><u> Factorise</u>
(x + 2)(x + 10)
<u>Step 3:</u><u> Find the roots / values of x</u>
Make each bracket equal zero.
(x + 2) = x = -2
(x + 10) = x = -10
Hope this helps!

Step-by-step explanation:
Answer:
So, marta will sprint 225 yards.
Step-by-step explanation:
Area of parallelogram= b*h
Given: Area = 776.5 square yards
Base = 34.5 yards
Area = b* h
776.5 = 34.5 * h
776.5/34.5 =h
=> h = 22.5
Since sprint is the same distance as of height of park so,
Distance of 1 sprint = 22.5 yards
Distance of 10 sprints = 10 * 22.5 = 225 yards
The answer is b or d you choose
