The expression (2x+2x)+(5x+5x)+(1+1) represents the perimeter of a triangle. Select the answer below which shows this expression
Maru [420]

Answer:

A) 14x + 2

Step-by-step explanation:

(2x + 2x) + (5x + 5x) + (1 + 1)

= 4x + 10x + 2

= 14x + 2

You can only add 4x and 10x since they both have a variable (x). You cannot add 2 since 2 doesn't have a variable, so the answer in simplest form is 14x + 2

One leg of a right triangle is twice as long as the other. write the length of the hypotenuse
rusak2 [61]
Let one of the legs be called x. 

The second leg= 2x 

You know that; c²=a²+b²

c²=(2x)²+(x)²
c²=4x²+x²
c²=5x²
c=√5x²

Therefore, the length of the hypotenuse should be √5x².

Hope I helped :)
