Y² + 14y + 49 = 0
We know a² + 2ab + b² = (a + b)²
(y)² + 2 x 7 x y + (7)² = 0
(y + 7)² = 0
y = -7
y = -7

Answer:
1.2 t/m³
Step-by-step explanation:
1 tonne is 1 Mg = 10⁶ g
1 m³ is (100 cm)³ = 10⁶ cm³
The conversion is ...
(1.2 g/cm³) · (1 t)/(10⁶ g) · (10⁶ cm³)/(1 m³)
= 1.2(10⁶)/(10⁶) t/m³
= 1.2 t/m³
__
For this conversion, the numerical value does not change. Megagrams per cubic meter is the same ratio as grams per cubic centimeter.
Answer:
h=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
-7=(-10-h)/(7-6)
-7=(-10-h)/1
-7*1=-10-h
-7=-10-h
h=-10-(-7)
h=-10+7
h=-3
84 divided by 32 = 2.6
42 divided by 96.6 = 2.3
And 38 divided by 102.6 = 3.2
SO THE ANSWER IS.....38 laps in 102.6 min
