Answer:
- 7040 yards
- zeros are place holders
Step-by-step explanation:
Each mile is 1760 yards, so 4 of them is ...
4 × 1760 yards = 7040 yards
__
This number is written as a decimal number in a "place value" system, so the position of the digit in the number tells its value.
In order for the 7 to indicate 7 thousand, it needs to be in the "thousands" place in the number. The 0s in the hundreds and units places are called "place holders" because they ensure the other digits appear in their proper places in the number.

If it were written in Roman Numerals, it would be 
. In this system, the letter tells its value (and "place" comes into account in XL, which means X is subtracted from L). The system of Roman Numerals has no zeros, and doesn't need them.
Answer: 2x³-10x²+12x or 2x(x²-5x+6)
Step-by-step explanation:
(p*q)(x) means p(x) and q(x) multiplied together.
(2x²-4x)(x-3)
2x³-6x²-4x²+12x
2x³-10x²+12x
You can also factor this by taking out a 2x.
2x(x²-5x+6)
Aas is not d triangle buddy
Step-by-step explanation:
In the problem 5 is raised to an odd exponent(9). Thus, there is no way to halve it apart from doing 5^4.5, which equals 1397.54249, which is not a whole number.
Hope it helps <3
I'm tempted to separate this inequality into two parts:
x > 0 and 0 < y + z.
x > 0 includes all of the 3-dimensional solid to the right of the plane x = 0.
If 0 < y + z, then -y < z, or z > -y. z = -y is the equation of a plane that is good for all x (x doesn't matter here). Draw the plane (thru the origin) that satisfies z = -y. Then 0 < y + z denotes the portion of the 3-d solid BELOW the plane z = -y.
Best to draw this in 3-d and to shade the portions of the solid centered at (0, 0, 0) that satisfy both x > 0 and 0 < y + z.
