When Theresa got her puppy, it weighed 6 ponds less than 2/3 of its weight now. If the puppy weighed 4 pounds when she first received himnwhat is her puppys weight now

15 lb

Step-by-step explanation:

let the current weight of the puppy be X, the  initial weight of the puppy is 4lb or , (6 lb less 2/3 X) .

#We equate the current weight to the initial weight to determine X:

Hence, the current weight of the puppy is 15 lb

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
