X is -2,first x plus 10x plus 22 equals 0,so if plus 22 is zero than x minus 10x than plus 22 than you got it,0
Step-by-step explanation:
The 3rd interior angle of the triangle can be written as
The angle above is supplementary to the angle (2x - 2), therefore
Solving for x, we get
Answer:
A building is 35 feet tall
35
The scuba diver is 35 feet below sea level
-35
The basement is 7.6 feet below ground
-7.6
Oliver owes his sister $23

Step-by-step explanation:
You have to look at the word choice, like below or tall. If they are describing something below something else they generally want it to be negative, or if they are talking about how much you owe. Otherwise it will be positive. Then just match the numbers.
-4.2 x + 3 = -1.2x and 2.5x - 6 = -3.5 x
Answer:
Step-by-step explanation:
From the given information:
The domain D of integration in polar coordinates can be represented by:
D = {(r,θ)| 0 ≤ r ≤ 6, 0 ≤ θ ≤ 2π) &;
The partial derivates for z = xy can be expressed as:
Thus, the area of the surface is as follows:
