4 x 3/5
4/1 x 3/5
4x3/5x1
12/5kg of corn a week
(12/5)/7
12/5(1/7)
12/5x7
12/35kg per day
The correct answer is A.
Here is the completed problem:
3(4x+5)=12
Distributive property.
3(4x+5)=12
Simplify
12x+15=12
Subtract 15 from both sides.
12x+15−15=12−15
12x=−3
Divide both sides by 12.
12x/12 = −3/12
x= −1/4
7 minutes per mile so around 2.5 miles

Answer:
Step-by-step explanation:
Check if the relationship is linear. Verify the difference between areas.
We can see the difference is not common.
It means we can exclude options B and C.
The remaining options are quadratic (A and D).
<u>Try the last column with option A:</u>
- 4813 = 45² + 1908
- 4813 = 3933
- False
<u>Verify the last option:</u>
- 4813 = 45² + 44*45 + 808
- 4813 = 4813
- Correct
We can check and confirm the other columns are correct as well.
