Sever21 [200]3 years ago
3 0

Answer:

Perimeter = 34ft Area = 72ft squared

Step-by-step explanation:

The perimeter of an object is all of it's sides combined. Because you stated two values, I assumed your shape is a rectangle. So the perimeter would be:

8 + 8 + 9 + 9 = 34

The area is length times width, so:

8 x 9 = 72

Because it is area, the units are squared.

In Triangle LMN, angle N is a right angle, LM=76 and MN= 40. What is the measure of angle M?
kogti [31]
The quastion is asking us to determine the measure of angle M in a right triangle LMN. We know that angle N is a right angle and that LM = 76 ( Hypotenuse ) and MN = 40 ( Adjacent ). We will use trigonometry: cos M = Adjacent / Hypotenuse = 40 / 76 = 0.5263158; M = cos^(-1) 0.563158; M = 58.242° = 58° 15`. Answer: The measure of angle M is<span> 58°15`.</span>

If f(x) = 5x – 3 and g(x) = 3x – 3, find f(x) – g(x). Please include full explanation
Kisachek [45]

Answer:

2x

Step-by-step explanation:

f(x) – g(x)

f(x) = 5x – 3 and g(x) = 3x – 3

f(x)- g(x) = 5x – 3 -( 3x – 3)

Distribute the minus sign

               5x -3 -3x+3

Combine like terms

              5x-3x-3+3

               2x
