Answer:
y = 2x² + 16x + 11
Step-by-step explanation:
first foil (x + 4)² to get x² + 8x + 16
distribute 2 to get 2x² + 16x + 32
subtract 21 from 32
Answer:

Step-by-step explanation:
The formula of a volume of a sphere:

R - radius
We have R = 3 ?. Substitute

If the radius is 30, then the volume is:

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:

Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
the answer is 60.
all you have to do is multiply all the numbers.
3 × 4 × 5 = 60
first:
multiply two of the numbers together. anything you like.
4 × 3 is 12
and now multiply the left number with the
result.
which is
5 × 12 = 60
A common logarithmic provides the following value for the log10 of 8.65:
<span><span>0.9370161
Which number is closest to this one?
The answer is D) 0.9370.
This means that 8.65 = 10^(.9370). Note that that the number is less than 1, since 10^1 is 10, and 8.65 is less than 10. </span></span>
