Step-by-step explanation:
Using FOIL,
(2 + √3)(1 + √3)
= (2)(1) + (2)(√3) + (√3)(1) + (√3)(√3)
= 2 + 2√3 + √3 + 3
= 5 + 3√3.
41, 50, 59
all you have to do is subtract the first number from the second number which is 9. then you add 9 to the last number to get your answer
Altitude, like elevation, is the distance above sea level. Areas are often considered "high-altitude" if they reach at least 2,400 meters (8,000 feet) into the atmosphere. ... This is called indicated altitude, and is measured by an instrument called an altimeter. As altitude rises, air pressure drops.
Answer:
Priya is correct. Because 2/3 is being added to x and not multiplied, then subtracting 2/3 from both sides is the correct action.
Step-by-step explanation:
Let's run through solving it that way:
2/3 + x = 4
2/3 - 2/3 + x = 4 - 2/3
0 + x = 4 - 2/3
x = 4 - 2/3
x = 10/3
