2^2-3(-2)+1 evaluate the polynoimal

We must follow order of operations rules (PEMDAS) here: exponentiation first, followed by multiplication and division, followed by addition and subtraction.

Thus, -2^2-3(-2)+1 becomes:

-[4] + 6 + 1 = 2 + 1 = 3 (answer)

b

step-by-step explanation:

b

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.
