If the tiger has consumed 70 pounds of food in 10 days that's \( \frac{70}{10} \) = 7 pounds of food per day. The tiger needs to consume 105 - 70 = 35 more pounds of food to reach 105 pounds total. At 7 pounds of food per day that's \( \frac{35}{7} \) = 5 more days.

To multiply terms with radicals, multiply the coefficients and radicands separately:

7\( \sqrt{5} \) x 7\( \sqrt{9} \)
(7 x 7)\( \sqrt{5 \times 9} \)
49\( \sqrt{45} \)

Now we need to simplify the radical:

49\( \sqrt{45} \)
49\( \sqrt{5 \times 9} \)
49\( \sqrt{5 \times 3^2} \)
(49)(3)\( \sqrt{5} \)
147\( \sqrt{5} \)

By buying two shirts, Ezra will save $34 x \( \frac{45}{100} \) = \( \frac{$34 x 45}{100} \) = \( \frac{$1530}{100} \) = $15.30 on the second shirt.

First, solve for \( \left|x + 5\right| \):

\( \left|x + 5\right| \) + 8 = -4
\( \left|x + 5\right| \) = -4 - 8
\( \left|x + 5\right| \) = -12

The value inside the absolute value brackets can be either positive or negative so (x + 5) must equal - 12 or --12 for \( \left|x + 5\right| \) to equal -12:

So, x = 7 or x = -17.

The factors of a number are all positive integers that divide evenly into the number. The factors of 64 are 1, 2, 4, 8, 16, 32, 64.
