Which expression has a value of 13? (20 ÷ 4) − 4 + 3 x 2 (18 ÷ 2) + 6 ÷ 6 + 3 (16 ÷ 4) + 3 x 4 − 1 (10 ÷ 2) − 3 + 4 x 2

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

i cant answer this, theres no table. sorry man

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
