The lengths of all sides of a triangle are integers when measured in decimeters. One of the sides has length of 1 dm and another
hram777 [196]

Answer:

The perimeter is 7 dm

Step-by-step explanation:

we know that

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let

c------> the length of the third side

case a)

1+c>3

c>2 dm

case b)

1+3> c

4 > c

rewrite

c<4 dm

The solution for c is the interval------> (2,4)

therefore

the value of c must be equal to

c=3 dm (because is an integer)

The perimeter is equal to

P=1+3+3=7 dm

100 POINTS AND BRAINLIEST: The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than
Wittaler [7]

Answer:

x= "a certain number of inches"

side a= x-3

side b= 2 inches

multiply:

Area= a(b)

A= (x-3)2

A= 2(x-3)

distribute:

A= 2(x-3)

A= (2*x) + (2*-3)

A= 2x-6

Area= 2(x-3)

Area= 2x-6

Step-by-step explanation:

The area of the rectangle is equal to the multiple of its two sides this is equal to two inches times an expression three less than a certain number "x". Using the distributive property, we can solve this expression further to find that the area of this rectangle is also equal to six less than doubling a certain number x.
