Answer:
16.92
Step-by-step explanation:
4 + 12.92 =
16.92
Answer:
theyre not because it becomes 32 +x and 37+3x

communitive
11x+12
6p+35
2(b+8)+2(3b)
8b+16
perimeter is the length of all sides so it would be b+8 and 3b two times since each side is equal

The angles of elevation and depression are formed by the line of sight and the horizontal line. When the line of vision is above the horizontal line, the angle is of elevation, and if the line of sight is below the horizontal, the angle is of depression.
The angle of depresion from the top of the taller building and the angle of elevation from the top of the shorter building are alternate interior angles. Then, if the angle of depression of the taller building is 15° the angle of elevation of the shorter building is 15° too. To understand this, you should see the diagram attached.
In the diagram you can notice that both angles, of elevation and depression, have the same value.
Then, the answer is:
The angle of depresion from the top of the taller building and the angle of elevation from the top of the shorter building are alternate interior angles.
Answer:
2.871*10^9
Step-by-step explanation:
add a decimal point at the end of the number ( 2,871,000,000.) then count how many places it takes to move the decimal point between the first and second number (2.8) then write the rest of the numbers higher than "0" after, giving you the 2.871
to show that the number written is in scientific notation you add 10 to the power of the amount of times you moved the decimal place. In this case, because the decimal point was moved a total of 9 times, it would be 10 to the 9th power (10^9).
Answer is C.
All real numbers
