(4/9)² ÷ ( 1/3 + 2/9 – ½) this is an order of operation with exponet problem
please show work and explain how you got the answer

When using the order of operations to solve the problem, then the final answer will be

Step-by-step explanation:

÷

Following the order of operations, the first thing we have to do is add 1/3 to 2/9 and then subtract that sum by 1/2.

÷

÷

Next, we solve the exponent on 4/9 by multiplying 4/9 with itself.

÷

Lastly, we divide 16/81 by 1/18.

÷ =

Since this number can not be simplified into a smaller fraction, then the answer will stay as it is.

So, your final answer will be

answer: (1,3) and (-2,0) i think.

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.
