The rules of operations states that we deal with parentheses first. So, inside the parentheses, we have, 2 times 3. Multiply that. That gives us 6. So now, the equation looks like this:

(6)^2 + 5^2

Now we have to work with the exponents. So, square both numbers.

(6)^2 = 36

5^2 = 25

Now we have:

36 + 25

Now we add. 36 + 25 = 61

61 is your answer.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
