Answer:
greg, 4 seconds
Step-by-step explanation:
find how long it takes each person to run 2km first.
distance/speed:
- pepper: 2/3 *60(seconds)=40 seconds
- Greg: 2/5 *60= 24 seconds
40-12=28 seconds, pepper will take 28 seconds to finish the race from the time greg starts. greg will win by 4 seconds
1. a² + 8a = 0
a(a) + (8) = 0
a(a + 8) = 0
a = 0 or a + 8 = 0
- 8 - 8
a = -8
2. (3h - 6)(2h - 8) = 0
(3(h) - 3(2))(2(h) - 2(4)) = 0
(3(h - 2))(2(h - 4)) = 0
6(h - 2)(h - 4) = 0
6 6
(h - 2)(h - 4) = 0
h - 2 = 0 or h - 4 = 0
+ 2 + 2 + 4 + 4
h = 2 h = 4
3. 6m² + 17m + 5 = 0
6m² + 15m + 2m + 5 = 0
3m(2m) + 3m(5) + 1(2m) + 1(5) = 0
3m(2m + 5) + 1(2m + 5) = 0
(3m + 1)(2m + 5) = 0
3m + 1 = 0 or 2m + 5 = 0
- 1 - 1 - 5 - 5
3m = -1 2m = -5
3 3 3 3
m = ⁻¹/₃ m = -1²/₃
4. y² - 36 = 0
y² - 6y + 6y - 36 = 0
y(y) - y(6) + 6(y) - 6(6) = 0
y(y - 6) + 6(y - 6) = 0
(y + 6)(y - 6) = 0
y + 6 = 0 or y - 6 = 0
- 6 - 6 + 6 + 6
y = -6 y = 6
5. (3g + 4)² = 0
(√(3g + 4))² = √(0)
3g + 4 = 0
- 4 - 4
3g = -4
3 3
g = -1¹/₃
Answer:
then where is the question
have a great dayy
