The perimeter of a triangle is 122 centimeters. If two sides are equally long and the third side is 8 centimeters longer than the others, find the lengths of the three sides.

Answers

Answer 1

Answer:

2 sides are 38cm long

The third is 46cm long

Step-by-step explanation:

We can use the following equation to solve

[tex]122 =x + x + (x + 8)[/tex]

Reduce

[tex]122 = 3x + 8[/tex]

114÷3 = x

x = 38

We then add 38 and 8 because the 3rd side is 8cm longer

Answers

Answer:

330 + 33 = 363

Step-by-step explanation:

The answers you are looking are 330 and 33.

If you were to take 330 and 33 and add them together, it would equal 363. The question also states if you were to take the 0 off of the first number (330), youd get your second number (33) to equal the sum given.

- Mia and Lily are trying to find the nearest whole number to the square root of 120

Mia: It is 10
Lily: It is 11

Who is correct?

Give a reason for your answer.​

Answers

Lily is correct

11x11=121 and 10x10 is 110 so the nearest number of the square root 120 is 11.

For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Given that,

Mia has 10 number.And,  Lily is 11 number.

Now if we square both the numbers so it comes:

10^2 = 10011^2  = 121

So, 121 is nearest to 120.

Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
