Answer:
The solution set is {-8, 5}.
Step-by-step explanation:
a^2 + 3a – 40 = 0 .
We need 2 numbers whose product is -40 and whose sum is +3.
They would be + 8 and - 5, so we have the factors:
(a + 8)(a - 5) = 0
Now either a + 8 = 0 or a - 5 = 0, so:
a = -8 or 5.
Using the Pythagorean Theorem, we have that the distance from home plate to second base is about 127 feet.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs
and
of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the <u>sum of the legs squared</u> of the triangle, according to the following equation:

The distance between each consecutive base is of 90 feet, hence the distance from home plate to 2nd base is the hypotenuse of a <u>right triangle in which the legs are of 90 feet</u>, being the distances from home plate to 1st base and 1st base to 2nd base.
Then:
h² = 90² + 90²
h = sqrt(90² + 90²)
h = 127 feet.
The distance from home plate to second base is about 127 feet.
