3) Can the following be lengths of the sides of a triangle? Why or why not?
a. 12, 15,3
b. 8. 8,5

b can be

a can not be

Step-by-step explanation:

the sides of a triangle have to add up

for example a can not be because 12 + 3 = 15 and that is the same length of one of the sides

but

b can be because 8 + 5 = 13 and that is greater than all of the sides

i hope this helps

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
