Answer:

First option: Nine mutiplied by the difference of eighty-six and a number.

Step-by-step explanation:

We have the expression:

9(86−x)

We have a difference of number in parenthesis, meaning that this operation will happen first, and then its result will be multiplied by 9

So, we know that this expression means that 9 will be multiplied by something, and this something is a difference of 86 and a number (86 first, and the other number second).

Then, the correct answer would be:

Nine mutiplied by the difference of eighty-six and a number.

First option is the correct one.

The area of triangle ABC is _____.

SEE ATTACHED IMAGE.
Using Heron's Formula we can find the area of the triangle.
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Where,
s: semi-perimeter
a, b, c: sides of the triangle
Substituting values:
s = (15 + 16 + 20) / 2
s = 25.5
s = 26
The area will be:
A = root (26 * (26-15) * (26-16) * (26-20))
A = 130.9961832
A = 130 u ^ 2
Answer:
The area of triangle ABC is:
C.
130 u ^ 2
