**Answer:**

18 yards

**Step-by-step explanation:**

Area of park = 324 Square yards

You factor them both.. make them = to 0

**Answer:**

Given that the events A and B are mutually exclusive.

P(A) = 0.1

P(B) = 0.4

**Mutually Exclusive Events**: When two events are Mutually Exclusive it is impossible for them to happen together i.e

If A and B are two events then; P(A and B) = 0

then;

P(A or B) = P(A) +P(B)

**By the definition of mutually exclusive events**;

P(A or B) = P(A) +P(B) ......[1]

Substitute the values of P(A) = 0.1 and P(B) = 0.4 in [1] we have;

**P(A or B) = P(A) +P(B) = 0.1+0.4 = 0.5**

The answer is B maybe try it?

The answer is B.

Do you need the explanation?

<span> (3x^3 - 7x^2 + 12) - (3x^3 + 6x^2 + 10x)

</span>First, remove parentheses

3x^3 - 7x^2 + 12 - 3x^3 -6x^2 -10x

eliminate the opposites

then collect the like terms

13x^2 +12 - 10x

and finally, use the commutative property to reorder the terms, and you'll get

-13x^2-10x+12
