Answer:
-a^2 - a + 12
Step-by-step explanation:
You only need to find the products of the first and last terms to determine the correct answer:
(-a)(a) = -a^2
(3)(4) = 12
You're looking for an expression with -1 as the leading coefficient and +12 as the constant. There is only one choice like that:
-a^2 - a + 12
<span>t's call P the number of art brushes that Monique has.
Chelsea has 11xP (that is 11 times as many as Monique)
Together they have:
P + 11xP = 12xP
That means 12xP = 60 (60 is the number of art brushes they have together)
In order to find how much is P, we need to divide:
60 Ă· 12 = 5 brushes
P = 5 ; that means has Monique 5 art brushes.
Chelsea has 11 times as many art brushes as Monique:
11 x 5 = 55 brushes</span>
