K² + 8k + 15
k² + 5k + 3k + 15
k(k) + k(5) + 3(k) + 3(5)
k(k + 5) + 3(k + 5)
(k + 3)(k + 5)
The answer is D.
3x + 4
2x + 5|6x² + 23x + 20
6x² + 15x

The answer is C.
(5d² + 4d - 3) - (3d² - 2d + 4)
(5d² - 3d²) + (4d + 2d) + (-3 - 4)
2d² + 6d - 7
The answer is B.
4b² - 9
4b² + 6b - 6b - 9
2b(2b) + 2b(3) - 3(2b) - 3(3)
2b(2b + 3) - 3(2b + 3)
(2b - 3)(2b + 3)
The answer is C.

Answer:
0.75
Step-by-step explanation:
Put the number where the variable is and do the arithmetic.
3(1.5² -2) = 3(2.25 -2) = 3(0.25) = 0.75
Answer:
1 / 20
Step-by-step explanation:
Brian = 11.74 seconds
Luis = 11.69 seconds
Difference between their times :
11.74 - 11.69 = 0.05
Expressed as a fraction of a second :
0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20
Same sign add different sign subtract that means if their both positive you add and if one is positive and the other is negative you subtract
