The perimeter of a triangle is 21.7 cm. Its side lengths are 10, 5.2, and x+2. Find the value of x.

x = 4.5.

Step-by-step explanation:

it is given that the perimeter of a triangle is 21.7 cm. Its side lengths are 10, 5.2, and x+2.

Perimeter of a triangle = Sum of its all sides.

Combine like terms.

Subtract 17.2 from both sides.

Therefore, the value of x is 4.5.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
