Help please

a) Scalene

b) Scalene

c) Isosceles

Step-by-step explanation:

Here, we want to get the type of triangle with the given side lengths

a) 2,5,4

All the side lengths are different, the triangle type is scalene triangle

b) 9,12,13

All side lengths are different, the triangle type is scalene triangle

c) 4,4,9

Two side lengths are equal

The triangle type is an isosceles triangle

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
