That I can not understand it looks weird.
31x^2 + 53x - 8
Use the FOIL method to find the area of the large rectangle. (7x - 2)(9 + 5x)
First term in each binomial: 7x * 9 = 63x
Outside terms: 7x * 5x = 35x^2
Inside terms: -2 * 9 = -18
Last term in each binomial: -2 * 5x = -10x
Now, just add them all up.
63x + 35x^2 - 8 - 10x
35x^2 + 53x - 8
Now find the area of the square.
2x * 2x = 4x^2
Now, subtract the areas.
31x^2 + 53x - 8

The volume of a rectangular prism is always LWH=V, the cube is a special prism in that L=W=H are all equal so:
V=s^3 where s is the length of all sides...
s^3=1728
s=1728^(1/3)
s=12 units
If x represents the number of flower baskets, then, just as you showed, the answer cant be either a or b because store A doesnt charge $15 per flower basket but rather $15 for delivery. To see whether it is c or d, simply use the same number to represent the number of flower baskets in both inequalities. The easiest would be 1 because then youre multiplying - in the case of store A - 19.25 (how much each flower basket costs) times 1 (the total number of flower baskets) and then adding 15 (the cost of delivery) which is a total of 34.25. For store B it would be 17.5 times 1 plus 30 which equals 47.5. Therefore, the inequality for store A is less than that of store B, so D would be the answer. (i hope that sort of makes sense sjdjdjjs)
Answer:
C, -50*hours+475
Step-by-step explanation:
We are trying to get the total distance left, so we are subtracting the distance traveled from the total. If we travel at 50 miles per hour then the distance traveled is equal to 50*hours and if you subtract that from the total you ahve the distance left.
