Answer:
6m²
Step-by-step explanation:
Because the question asks for the area of a face but it doesn't indicate which face then it can be any of the faces.
2m x 3m = 6m²
2m x 4m = 8m²
3m x 4m = 12m²
In your case one of the possible answers is 6m² - so that is the one they are looking for.

Synthetic division:
3 | 3 11 2 -7 61
. | 9 60 186 537
- - - - - - - - - - - - - - - - - - - -
. | 3 20 62 179 598
which translates to
i.e. you're left with a remainder of 598.
First, let's define the variables d and q as follows:
d: total number of dimes
q: total number of quarters.
"Joan has an equal number of dimes and quarters" means that d=q.
"...with <span>with a total value of $1.40</span>" means that
0.1 d + 0.25 q =1.40. ***
This is because Joan has a total of d dimes each with a value of 0.1$, and a total of q quarters, each with a value of 0.25.
Since d=q, we can write the equation *** as:
0.1 q +0.25 q=1.40
0.35 q=1.40
q=1.40/0.35 = 4.
Thus, Joan has a total of 4 quarters, and 4 dimes.
Answer: 8 coins.
