Answer: 4*(7+6), 4*7+4*6.
Step-by-step explanation:
The GCF, or greatest common factor, of 28 and 24, is 4.
So, what you would do is 4*(28/4+24/4)
You would get, 4*(7+6), 4*7+4*6.
Simplify:
2√20-2√5
A.)√5-√5
B.)2
C.)2√5
D.)4√4-√5
Answer:
To simplify the expression 2√20 - 2√5, you can start by applying the rule that the square root of a product is the product of the square roots of the factors. This means that you can rewrite √(20) as √(4*5) = 2√(5).
Applying this rule, the expression simplifies to:
2√(5) - 2√(5) = 2√(5) - 2√(5) = 0
Therefore, the simplified expression is equal to 2√(5).

Dominic says that the product of 827 and 53 is 43,511. Is his answer
correct? Explain.
No, Dominic's answer is incorrect.
To find the product of 827 and 53, you can use the standard multiplication algorithm that you would use for decimal numbers.
First, you need to multiply the rightmost digit of 53, which is 3, by 827. This gives you 2481.
Then, you need to multiply the next digit of 53, which is 5, by 827 and add this result to the previous one. This gives you 43,811.
Therefore, the product of 827 and 53 is 43,811, not 43,511 as Dominic has stated. Dominic's answer is incorrect because he has made an error in the calculation.

Find all x-intercepts and y-intercepts of the graph of the function.
f(x)=3x³-12x²-15x
Answer:
To find the x-intercepts and y-intercepts of a function, we need to find the values of x and y at which the function crosses the x-axis or y-axis.
X-intercepts:
The x-intercepts occur when y = 0, so we can set f(x) = 0 and solve for x:
3x³-12x²-15x = 0
This is a cubic equation, we can use factoring, synthetic division or use a numerical method like the Newton-Raphson method to solve for x.
Y-intercepts:
The y-intercepts occur when x = 0, so we can substitute x = 0 into the function to find the y-intercept:
f(0) = 3(0)³ - 12(0)² - 15(0) = 0
So the y-intercept of the graph is at the point (0,0)
In summary, the x-intercepts are the solutions of the equation 3x³-12x²-15x = 0 and the y-intercept is (0,0)
Please note that, if the equation has complex roots, the graph will not cross the x-axis and hence it will not have any real x-intercepts.

The graph
On the graph, we have the following readings (when the lines representing the rise and the run are drawn)
Length of rise = -9
Length of run = 3
The slope of the line is then calculated as
Slope = Length of rise/Length of run
Substitute the known values in the above equation, so, we have the following representation
Slope = -9/3

This is only true equation when A is equal to -2. Therefore, the correct answer is B) -2.
B) -2
The given system of equations can be written as:
Y = A*x^2 + 4*x - 4
We can solve this equation by using the Quadratic Formula. The Quadratic Formula states that the solutions to the equation are given by:
x = [-b +/- sqrt(b^2-4ac)]/2a
where a, b, and c are the coefficients of the equation. In this case, a = A, b = 4, and c = -4.
Substituting these values into the equation, we get:
x = [-4 +/- sqrt(4^2-4*A*(-4))]/2A
Simplifying this, we get:
x = [-4 +/- sqrt(16 + 16A)]/2A
For the system of equations to have two real solutions, the value of the square root must be greater than or equal to zero. This means that 16 + 16A must be greater than or equal to zero.
This is only true when A is equal to -2. Therefore, the correct answer is B) -2.

If the probability that each guest got one roll of each type ism/n where m and n are relatively prime integers, find the value of (m+n).
The probability that each guest got one roll of each type is 3/1, which is a fraction with a numerator of 3 and a denominator of 1. Since the numerator and denominator are relatively prime integers, the value of m + n is 3
The equation for the probability that each guest got one roll of each type is m/n, where m and n are relatively prime integers.
We can expand this equation to
m/n
= 3/1.
Since the numerator and denominator are relatively prime integers, we can solve for m + n by multiplying both sides of the equation by 1.
Multiplying both sides of the equation by 1 gives us
m + n = 3.
Therefore, the value of
m + n is 3.
Let m = numerator and n = denominator in the probability of m/n.
Given that each guest got one roll of each type, the probability is m/n.
The numerator and denominator are relatively prime integers, so m and n have no common factors.

Here is an illustration of a set of equations:
x + y = 7
x - y = 1
To determine whether a given point (x, y) is a solution to a system of equations, we need to substitute the values of x and y into the equations of the system and see whether the equations are satisfied.
In this case, we want to check if (1, 1) is a solution to the system of equations:
