Everything looks good until the final step. The answer is not c = 26. It should be more like c = 25.495 which is approximate. You would use your calculator to find this value. If you round to the nearest whole number, then c = 25; however, this is a bad idea because it implies that the hypotenuse is the same length as the longer leg, which is not the case here. Recall that the hypotenuse is always the longest side.
A. 168 m3
Step-by-step explanation:
V = Bh
V = 24(7)
V = 168 m3
X - the first numberx + 13 - the second number
The equation:
x + x + 13 = 152x + 13 = 15 |-132x = 2 |:2x = 1
x + 13 = 1 + 13 = 14
Answer: 1 and 14

-t(5t - 7) = -5
-1 -1
t(5t - 7) = 5
t(5t) - t(7) = 5
5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
2(5)
t = 7 ± √49 - 4(-25)
10
t = 7 ± √49 + 100
10
t = 7 ± √149
10
t = 0.7 ± 0.1√149
