What is 7c2 x 7c3?
| 49c5 | |
| 14c6 | |
| 14c5 | |
| 49c |
To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:
7c2 x 7c3
(7 x 7)c(2 + 3)
49c5
A tiger in a zoo has consumed 48 pounds of food in 8 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 84 pounds?
| 6 | |
| 8 | |
| 7 | |
| 2 |
If the tiger has consumed 48 pounds of food in 8 days that's \( \frac{48}{8} \) = 6 pounds of food per day. The tiger needs to consume 84 - 48 = 36 more pounds of food to reach 84 pounds total. At 6 pounds of food per day that's \( \frac{36}{6} \) = 6 more days.

The greatest common factor (GCF) is the greatest factor that divides two integers.
If \(\left|a\right| = 7\), which of the following best describes a?
a = 7 |
|
none of these is correct |
|
a = 7 or a = -7 |
|
a = -7 |
The absolute value is the positive magnitude of a particular number or variable and is indicated by two vertical lines: \(\left|-5\right| = 5\). In the case of a variable absolute value (\(\left|a\right| = 5\)) the value of a can be either positive or negative (a = -5 or a = 5).
