You are building a fence 13 ft long. on monday, you build 4 1/3 feet of the fence, and, on tuesday, 5 3/4 feet. how much of the fence do you still need to build?

4 1/3+ 5 3/4 =

4 4/12+ 5 9/12 =

9 13/12=

10 1/12

so right now 10 1/12 of the fence is built so 2 11/12 still need to be built

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

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
