The answer is C.
5c+2w= 12
(5 x 2 )+(2 x1)=12
10 + 2 = 12
7c + 4w=15
(7x1) + ( 4x2) = 15
7 + 8 = 15
Hope this helps. :)
Cross multiply
15/18 = x/100
100 • 15/ 18 = x
x = 83.333333 %
length, width, and height are (b+2), (b-2), (b+3)
Step-by-step explanation:
Doing what the problem statement tells you to do, you get ...
(b^3 +3b^2) -(4b +12)
= b^2(b +3) -4(b +3) . . factor each pair of terms
= (b^2 -4)(b +3) . . . . write as a product
= (b -2)(b +2)(b +3) . . . . use the factoring of the difference of squares
The three factors are (b-2), (b+2), and (b+3). We have no clue as to how to associate those with length, width, and height. We just know these are the dimensions of the box.

Answer: 6.5 inches
Step-by-step explanation:
From the question, we are informed that Claire is building a dollhouse where 1 inch on the plans is equivalent to 5 inches on the actual dollhouse.
If the house is to be 32.5 inches tall, the height be on the plans will be one-fifth of the actual dollhouse. This will be:
= 1/5 × 32.5
= 6.5 inches
