Answer:
2x^2+1
Step-by-step explanation:
4x^2+2-2x^2-1
Group like terms:
4x^2-2x^2+2-1
2x^2+2-1
2x^2+1
Answer:
2x^2 + 3
Step-by-step explanation:
Subtracting functions is similar to subtracting normal numbers. An easy way to do it is to put one over the other and then combine like terms.
4x^2 + 2
- 2x^2 - 1
= 2x^2 + 3
Even though it looks like you would do 2-1, the three is because you're adding -(-1) (aka 1) to 2.

Answers
Therefore the expression simplified using only positive exponents is 10h^4v^22.
Define positive exponents.An exponent's sign indicates how many times to multiply or divide a base number. A negative exponent indicates the opposite. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.
Define multiply and divide.A mathematical procedure called multiplication shows how many times a number has been added to itself. The multiplication symbol (x) or (*) are used to denote it. A mathematical process that shows how many equal amounts add up to a given number is called division.
To simplify the expression using only positive exponents, we need to make sure that all the exponents are positive.
We can simplify the expression:
(2h^7v^-3)/(5h^-4v^5)^-5
= (2h^7v^-3)/(1/(5h^-4v^5)^5)
= (2h^7v^-3) * (5h^4v^25)
= 10h^4v^22

If you solve the equation and get the same number as yourself, there are infinite solutions, and if you get the wrong equation, there is no solution.
Without graphing, how can you determine if a system of equations has one solution or an infinite number of solutions?You can see that both slopes are the same (-3). This shows that the lines are parallel without creating a graph. Therefore, the system of equations cannot be solved.

Answers
The surface area of the pyramid is 568 square inches.
What is the surface area of a square pyramid?The surface area of the square pyramid is defined as the total area covered by the surfaces required to make the square pyramid. The area is the space occupied by the square pyramid in two-dimensional planes.
The formula to calculate surface area will be calculated by the formula below,
SA=B+12(P × l)
Here, B is the area of the base, P is the perimeter of the base, and l is the slant height.
SA = ( 8 x 8 ) + 12 ( 8 x 4 + 10 )
SA = 64 + 12 ( 32 + 10 )
SA = 64 + 12 x 42
SA = 568 square inches

Two sides of a triangle measure 23 inches and 41 inches. Which cannot be the length of the remaining side?
Answers
Answer:
Anything over 64 inches.
Step-by-step explanation:
The Triangle Inequality states that each side of a triangle must be shorter than the sum of the other two sides.
If you call the sides a, b, c, then a + b > c, a + c > b, b + c > a.
23 + 41 = 64, so the third side must be shorter than 64 inches.

Define the unitary method.The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
What are ratios and proportions?An ordered pair of integers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you might express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.
Let x be the cost of one pair of incense.
We know that the total amount spent on apples and oranges is the same as the total cost of 12 pairs of incense. Therefore:
(cost of apples + cost of oranges) = 12x
We also know that the cost of the apples is 3x the cost of the incense, and the cost of the oranges is 2x the cost of the incense. Therefore, we can substitute these values into the equation:
(3x + 2x) = 12x
5x = 12x
x = 12/5 or 2.4
So the cost of each pair of incense is 2.4 in terms of x.

Answers
In the diagram below of triangle HIJ, K is
the midpoint of H J and L is the midpoint of
IJ. If KL= -3.2 + 39, and
HI = 6x + 18, what is the measure of HI?
Answers
Answer:
HI = 48 units
Step-by-step explanation:
By midpoint theorem,
"Line segment joining midpoints of two sides of a triangle measures the half of the third side of a triangle."
Since, KL is the segment joining midpoints of JH and JI,
[tex]KL = \frac{1}{2}(HI)[/tex]
-3x + 39 = [tex]\frac{1}{2}(6x + 18)[/tex]
-3x + 39 = 3x + 9
6x = 30
x = 5
Therefore, HI = 6x + 18
= 6(5) + 18
= 30 + 18
= 48
