Step-by-step explanation:
10x^3+24^2+14
2(5x^3+12x+7)
2x(5x^2+12x+7)
2x(x+1)(5x+7)
2x(2x+1)(5x+7)
The factors of 2x^2 + xy - 3y^2 are
A (2x - 3y)(x + y)
B (2x + 3y)(x - y)
C (2x - y)(x + 3y)
D (2x + y)(x - 3y)
Answer:
B. (2x + 3y)(x - y)
Step-by-step explanation:
[tex]2x^{2} +xy-3y^{2}[/tex] Write x y as a difference
[tex]2x^{2} +3xy-2xy-3y^{2}[/tex] Factor out x from the equation
[tex]xx(2x+3y)-yx(2x+3y)[/tex] Factor out 2x+3y from the expression
[tex](2x+3y)x(x-y)[/tex] <----- Answer
The factors of [tex]2x^2 + xy - 3y^2[/tex] are [tex](x - y) (2x+ 3y)[/tex].
What are factors ?Factors is a number or algebraic expression that divides another number or expression. i.e., with no remainder
We have,
[tex]2x^2 + xy - 3y^2[/tex]
Now,
Using the middle term split method,
[tex]2x^2 + xy - 3y^2[/tex]
Splitting the mid term;
[tex]2x^2 - 2xy + 3xy - 3y^2[/tex]
Now taking commons,
[tex]2x(x - y) + 3y(x - y)[/tex]
Now again taking common factors
We get,
[tex](x - y) (2x+ 3y)[/tex]
So, the factors of given expression are [tex](x - y) (2x+ 3y)[/tex].
Hence, we can say that the factors of [tex]2x^2 + xy - 3y^2[/tex] are [tex](x - y) (2x+ 3y)[/tex] which are given in option [tex](B)[/tex] .

Step-by-step explanation:
which table of values represent a linear relationship?
The equation of a line that represents the table is; y = 6x - 5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b. Where slope = m and b = y-intercept.
Since we know that the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
To find the linear equation first we need slope;
(m) = (y₂ - y₁)/(x₂ - x₁)
= (1 + 11)/(1 + 1) = 12/2
m = 6.
Now, we have to take any one of these coordinate points and construct an equation in slope-intercept form;
- 11 = 6(-1) + b.
- 11 = - 6 + b.
b = - 5.
Therefore, y = 6x - 5 is our equation. the correct table represent a linear relationship is 2nd.

If u^2=d, what does the square root property state that u is equal to?
Answer:
the square root of d
Step-by-step explanation:
if [tex]u^{2} = d[/tex] then the square root property would take the square root of each side of the equation. the square root of [tex]u^{2}[/tex] would just be [tex]u[/tex] because it's already squared and its exponent would just be cancelled out, while d would simply turn to [tex]\sqrt{d}[/tex].
meaning if [tex]u^{2} =d[/tex] then [tex]u=\sqrt{d}[/tex], because you've done the same thing to both sides of the equal sign, so they remain equivalent.
The square root property says the value of u²=d is u=±√d
What is Square Root?The square root of a number is defined as the value, which gives the number when it is multiplied by itself. The radical symbol √ is used to indicate the square root. For example, √16 = 4. The radical symbol is also called a root symbol or surds.
Given here: The expression u²=d
The square root of a number is a value, which on multiplication by itself, gives the original number. The square root is an inverse method of squaring a number. To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
Thus we have the given expression as u²=d
Taking square root on both sides we get u=±√d
Hence, The square root property says the value of u²=d is u=±√d

What is a number line?A horizontal line with uniformly spaced numerical increments is referred to as a number line.
The way the number on the line can be replied will depend on the numbers on the line.
The number's intended use is described in the question that goes with it, such as when graphing a point.
Locating numbers, comparing numbers, fractions and mixed numbers, decimals, integers, absolute value, addition, subtraction, inequalities, multiples, common denominators, and other mathematical concepts may all be taught using number lines, which are incredibly versatile manipulatives.
We have a number-line.
To find the number line that shows the solution, n > 0:
n is greater than 0.
At 0, there is an open dot circle.
And the line should be extended toward positive infinity.

Write a function to represent the situation. *
A. O d-10m
B. O d= m + 10
C. O d=10m +10
D. O dem
Answer:
A
step-by-step explanation:
"d" I take it means donations or amount donated so if it's 10 per mile ran or 10m then you would write the equation as d=10m so it's A. Hope You found this helpful :D
A function that represents the situation is d = 10m.
The correct option is A.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given:
At a fundraising event,
$10 is donated for every mile ran.

Answer:
p=7
Step-by-step explanation:
Let's solve your equation step-by-step.
3+5p−12=2p+12
Step 1: Simplify both sides of the equation.
3+5p−12=2p+12
3+5p+−12=2p+12
(5p)+(3+−12)=2p+12(Combine Like Terms)
5p+−9=2p+12
5p−9=2p+12
Step 2: Subtract 2p from both sides.
5p−9−2p=2p+12−2p
3p−9=12

3p−9+9=12+9
