Answer: The roses costed $9
Step-by-step explanation:
3 multiplied by 3 equals 9
1 multiplied by 6 equals 6
9+6=15
7v(4v2-8v+1)+8(4v2-8v+1)
28v3-56v2+7v+32v2-64v+8
Answer= 28v3 -24v2 -57v +8
Answer:
9 ft, 28 ft, 26 ft
Step-by-step explanation:
The perimeter is the sum of side lengths, so ...
P = a + b + c
63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths
63 = 7n . . . . . . simplify
9 = n . . . . . . . . divide by 7
4n -8 = 36 -8 = 28 . . . . second side length
2n +8 = 18 +8 = 26 . . . . third side length
The side lengths are 9 ft, 28 ft, 26 ft..
Yes.
1 inch = 2.54 centimeters, for example. These two dimensions are the same, but the units are different.
