Answer:

-142

Step-by-step explanation:

You seem to have an arithmetic sequence with first term -66 and common difference (-68-(-66)) = -2. The general term of such a sequence is given by ...

an = a1 +d(n -1) . . . . . for first term a1 and common difference d

We want to evaluate this equation for a1 = -66, d = -2, n = 39:

a39 = -66 -2(39 -1) = -66 -76 = -142

The 39th term is -142.

Find the area of a parallelogram with base 15 yards and height of 21 2/3

VARVARA [1.3K]

To find the area of a parallelogram, you use the area formula:

Area = Base * Height

Then, all you have to do is substitute in your known integers and solve. Therefore:

Area = 15 * 21 2/3

When we multiply these two numbers, we get

Area = 325 square yards or yards $yards^{2}$
