Answer:

-6

Step-by-step explanation:

1. Treat the problem like a subtraction problem because -2.5 + (-3.5) can be rewritten as -2.5-3.5

2. When adding or subtracting negative numbers, keep these rules in mind:

Same signs add and keep.

Different signs subtract.

Keep the sign of the higher number.

-2.5 -3.5 have the same sign, so add them up and keep the sign.

And you do get -6.

To determine the hypotenuse, use the formula a^2 + b^2 = c^2.

Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.

Next, plug this into your calculator to get 7921. Then square root 7921.

The length of a rectangle is three times its width. if the area of the rectangle is 300 yd2 , find its perimeter.
Svetradugi [14.3K]
Let, width = x
Length = 3x

It is given that, 3x * x = 300
3x² = 300
x² = 300 / 3
x = √100
x = 10
& 3x = 3(10) = 30

Perimeter = 2(l + w)
P = 2(10 + 30)
P = 2(40) = 80

In short, Your Answer would be 80 Yards

Hope this helps!

<h2><u>x = (-6)</u></h2>
