How many truckloads will be left after 2 days?
Answer: 30 truckloads
Multiply 8 by 2.
8(2)
16
Then 46 minus 16
46-16=30 truckloads
After 3 days?
Answer: 22 truckloads
Multiply 8 by 3
8(3)
24
Then 46 minus 24
46-24=22 truckloads
When will more need to be ordered?
Answer: 4 days
Find the closest # to 46 that's a multiple of 8 and has more than 16 left over:
8,16,24,32,40,48
40 is the closest, but has more than 16 leftovers. So the next one would be 32. If you subtract 32 from 48, you have exactly 16 left. 32 is the 4th multiple of 8, so there would be 4 days until they need a refill.
Answer:
It will be 8

Answer:
(5a−3)^2
Step-by-step explanation:
25a^2 - 30a + 9
Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.
p+q=−30
pq=25×9=225
Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.
−1,−225
−3,−75
−5,−45
−9,−25
−15,−15
Calculate the sum for each pair.
−1−225=−226
−3−75=−78
−5−45=−50
−9−25=−34
−15−15=−30
The solution is the pair that gives sum −30.
p=−15
q=−15
Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).
(25a^2−15a)+(−15a+9)
Factor out 5a in the first and −3 in the second group.
5a(5a−3)−3(5a−3)
Factor out common term 5a−3 by using distributive property.
(5a−3)(5a−3)
Rewrite as a binomial square.
(5a−3)^2
