Answer:
(x+4)(x-5)
Step-by-step explanation:
You need to find two numbers that multiply to be -20 but add up to be -1.
4 Bacteria double per hour to give 8 bacteria then in 8 hours it will become 64 then this 64 doubles to give us 128
A. False. The data is quantitative because we're dealing with numeric values instead of things like names, colors, etc.
B. False. The row categories are "students" and "teachers"
C. True. This value (2) is in the "teachers" row and "does not wear glasses" column.
D. False. The value 32 represents the number of students who wear glasses. See row1, column1
E. True. Look at the last value of the "teachers" row.
===================================================
In summary, the answers are: C and E
The least it could weigh would be 4 tons by rounding 4.4 down
The most it could weigh would be 8 tons by rounding 7.7 up.
We are given the following equation and want to find which value of x will make it true:
Subtract 3 from both sides
Divide both sides by -6
Thus, the value that will make 3-6x=21 is x=-3. Let me know if you need any clarifications, thanks!
