Money spent = money spent on rose + money spent on daisies
# of roses = # of daisies + 3
or
$15 = 3r + 1d
r = d + 3 or d = r - 3
$15 = 3r + (r - 3)
15=4r - 3
4r=12
r = $3
Answer:
3x² + 30x
Step-by-step explanation:
width of a box = x units.
height of a box = 3 units.
length of a box = (x + 10) units.
Volume of the box = length × width × height
= (x + 10) * x * 3
= (x + 10) * 3x
= 3x² + 30x
Volume of the box = 3x² + 30x
