What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
We have,
20
The three expressions that are equal to 20 using only 4, -2, and 10 are:
First expression:
4 x 2 - (-2) + 10
= 8 - (-2) + 10
= 8 + 2 + 10
= 20
Second expression:
4 x 10 + (-2) x 10
= 40 - 20
= 20
Third expression:
-2 x (-2) + 4x4
= 4 + 16
= 20
Thus,
The three expressions that use only 4, -2, and 10 and that are equal to 20 are:
4 x 2 - (-2) + 10
4 x 10 + (-2) x 10
-2 x (-2) + 4x4

x ^ 2–2x + 1
by splitting this equation
x ^ 2 - x -x + 1
there are a two terms x ^ 2 - x and - x + 1
we take x is common from first and -1 is common from second
x ( x - 1 ) and -1 ( x-1 )
the quadratic roots are (x-1) and (x-1)
x - 1 = 0
x = 1 in both
Therefore , the quadratic roots are 1 , 1 .

Write an exponential expression: choose a number between 0 and 10 to be the base and another number between 0 and 10, different from the base, to be the exponent. Label the base and the exponent. Then write the exponential expression in expanded form and standard form.
Answer:
2^4
2 * 2 * 2 * 2
Step-by-step explanation:
In the question above :
Write an exponential expression:
Base = number between 0 and 10
Exponent = number different from the base between 0 and 10
Let base = 2
Let exponent = 4
Hence, exponential expression will be
Base^exponent
2^4 (standard form)
Expanded form:
2 * 2 * 2 * 2 (multiply 2 in 4 places)

In a recent year, 23% of all college students were enrolled part-time. If 6.2 million college students were enrolled part-time that year, what was the total number of college students?
Answer:
17,222,222
Step by Step Solution:
If 26% equals 6,200,000, then
1% equals 6,200,000/23, and
100% equals (6,200,000/23)*100 = 17,222,222.222222222222222222222222
Hence, there were about 17,000,000 (seventeen million) students.
To be a bit closer to the number, there where about 17,222,222 students.

Find the Area and Perimeter of the figure below.
6 cm
4 cm
2 cm
3 cm
Answer:
Area: 40cm^2
Perimeter:24cm
Step-by-step explanation:
Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.
Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

The average smoker typically pays 15% higher life insurance costs than the average non-smoke. If the monthly cost to a non-smoker is $500 dollars per month, how much would the average smoker pay per month for the same life insurance policy?
Answer:
$600 for a smoker
Step-by-step explanation:
On average, smokers will typically pay 15-20% higher premiums than non-smokers with equivalent demographics and health conditions. If the monthly premium for a non-smoker is $500 per month, it will be upwards of $600 for a smoker. The health insurance companies face a double-edged sword when it comes to insuring smokers.
