Answer: Yolanda's mistake is that she is assuming 105 is same as 10 x 5 .
Explanation:Here 105 represents a three digit number where 1 is at hundreds place,0 is at tens place and 5 is at once place and it can be written as the product of its factors 5 and 21 i.e 105=5×21 =21+21+21+21+21+21=105(by adding once place and tens place), where as 10×5 represents 5 times number 10 i.e.10+10+10+10+10=50(by adding once place and tens place)
So ,assuming 105 is same as 10 x 5 is her mistake.

Clint picks 13 apples. Tim picks 5 fewer apples than clint picks. How many apples does clint pick
Final answer:
To find out how many apples Clint picked, we need to first determine how many apples Tim picked. Clint picked 13 apples.
Explanation:
To find out how many apples Clint picked, we need to first determine how many apples Tim picked. It is given in the question that Tim picked 5 fewer apples than Clint.
So, we can subtract 5 from Clint's total apples to get Tim's total apples.
Next, to find Clint's total apples, we can add the number of apples Tim picked to the 5 fewer apples. This will give us Clint's total apples.
Let's solve the problem step-by-step:
Clint picked 13 apples.
Tim picked 5 fewer apples than Clint, which is 13-5 = 8 apples.
Clint's total apples = Tim's apples + 5 fewer apples = 8 apples + 5 apples = 13 apples.
Therefore, Clint picked 13 apples.

Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=
ANSWER
[tex](25\times9)+(75\times9)=9(25+75)[/tex]
[tex](25\times9)+(75\times9)=9(100)[/tex]
[tex](25\times9)+(75\times9)=900[/tex]
EXPLANATION
According to the distributive property,
[tex](a\times b)+(a\times c)=a(b+c)[/tex]
This implies that,
[tex](25\times9)+(75\times9)=9(25+75)[/tex]
[tex](25\times9)+(75\times9)=9(100)[/tex]
The Right Hand Side of the equation now has 2 factors.
We solve now to obtain;
[tex](25\times9)+(75\times9)=900[/tex]
The distributive property allows you to factor out a common factor from both terms in an equation. In this case, you can rewrite the expression (25x9)+(75x9) using the distributive property as 9*(25+75), which simplifies to 9*100 or 900.
Explanation:The distributive property in mathematics is a property where each term inside a bracket is multiplied by the term outside the bracket. We can use the distributive property to rewrite the given expression (25x9)+(75x9).
First, recognize that both terms in the equation have a common factor of 9. By applying the distributive property, you can factor out the common factor of 9 to get 9(25 + 75). Next, simplify the expression inside the parentheses (25 + 75) to get 100. So, your expression is now 9*100. Finally, multiply 9 by 100 to get 900. So, (25x9)+(75x9) = 900.Learn more about Distributive Property here:https://brainly.com/question/6276874

C. 60=2+5N
D. 60=2+5/N
If 60 is 2 more than the product of 5 and N:
The product of 5 and N is when they are multiplied, so 5N is going to be part of the equation.
We know that 60 is 2 more than 5N, so 5N + 2 would be 60.
We can make an equation with this:
60 = 2 + 5N
Therefore, the equation would be 60 = 2 + 5N.
Hope this helps! :)
The equation that can be used to depict the information 60 is 2 more than the product of 5 and N will be 60 = 2 + 5N
From the information given, 60 is 2 more than the product of 5 and N and this will be written as 60 = 2 + 5N.
To further solve the equation, we can solve for N and this will be:
60 = 2 + 5N
Collect like terms
5N = 60 - 2
5N = 58
N = 58/5
N = 11.6
Therefore, the value of N will be 11.6.
In conclusion, 60 is 2 more than the product of 5 and N and this will be written as 60 = 2 + 5N.

Given 5x3+8x2−7x−6. 1) The binomial (x+2) is a factor of the polynomial expression. Describe how you know it is a factor. 2) The binomial (x+1) is NOT a factor of the polynomial expression. Explain how you know it is not a factor.
ANSWER TO QUESTION 1
Given
[tex]f(x)=5x^3+8x^2-7x-6[/tex]
We can use the factor theorem to determine if
[tex]x+2[/tex] is a factor of the polynomial or not.
According to this theorem, if [tex]x+2[/tex] is a factor of [tex]f(x)[/tex], then [tex]f(-2)=0[/tex].
How did we get the [tex]-2[/tex]?
We set [tex]x+2=0[/tex] and then solve to obtain [tex]x=-2[/tex].
So now let us plug in [tex]x=-2[/tex] in to the function to see if it will simplify to zero.
[tex]f(-2)=5(-2)^3+8(-2)^2-7(-2)-6[/tex]
[tex]f(-2)=5(-8)+8(4)+7(2)-6[/tex]
[tex]f(-2)=-40+32+14-6[/tex]
[tex]f(-2)=6-6[/tex]
[tex]f(-2)=0[/tex]
Since the result simplifies to zero, we conclude that
[tex]x+2[/tex] is a factor of
[tex]f(x)=5x^3+8x^2-7x-6[/tex]
ANSWER TO QUESTION 2
We have the function,
[tex]f(x)=5x^3+8x^2-7x-6[/tex]
We can use the remainder theorem to show that
[tex]x+1[/tex] is NOT a factor of the polynomial.
According to this theorem, if [tex]x+1[/tex] is not a factor of [tex]f(x)[/tex], then [tex]f(-1)\ne 0[/tex].
So now let us plug in [tex]x=-1[/tex] in to the function to see if it will simplify to non-zero number.
[tex]f(-1)=5(-1)^3+8(-1)^2-7(-1)-6[/tex]
[tex]f(-1)=5(-1)+8(1)+7(1)-6[/tex]
[tex]f(-1)=-5+8+7-6[/tex]
[tex]f(-1)=4[/tex]
[tex]f(-1)\ne0[/tex]
Since the result simplifies to a non zero number, we conclude that
[tex]x+1[/tex] is NOT a factor of
[tex]f(x)=5x^3+8x^2-7x-6[/tex]

subtract 3 on both sides
-3x < -15
divide by -3 on both sides
x> 5
4x-12<20
add 12 on both sides
4x <32
divide by 4
x<8
x>5 and x<8

Given: △MOP, Perimeter of △MOP=12+4 sqr rt. 3 m∠P=90°, m∠M=60° Find: MP
Consider triangle MOP. This triangle is right triangle, because m∠P=90°.
Since m∠P=90°, m∠M=60°, then m∠O=180°-90°-60°=30°.
The leg opposite to the angle with measure 30° is half of the hypotenuse. Let the leg MP=x, then the hypotenuse MO=2x. By the Pythagorean theorem,
[tex]PO^2+MP^2=MO^2\Rightarrow PO^2=(2x)^2-x^2=4x^2-x^2=3x^2\Rightarrow PO=\sqrt{3}x.[/tex]
The perimeter of triangle MOP is
[tex]P_{MOP}=MO+PO+MP=x+2x+\sqrt{3}x=3x+\sqrt{3}x.[/tex]
Since [tex]P_{MOP}=12+4\sqrt{3},[/tex] then [tex]x=4.[/tex]
Answer: MP=4 units.
Answer:
mp=4 cuz in a 30-60-90 degree right triangle if the shorter leg is x, then the longer leg (po) is xsqrt3. Because the perimeter is 12+4sqrt3, that means the longer leg is probably 4sqrt3. because of this, then the shorter leg, mp is 4. Since the hypotenuse is equal to 2x, then it would be 2*4=8=PO.

Find a cubic function with the given zeros. (5 points)
-2, 5, -6
The cubic function with zeros -2, 5, and -6 is given by f(x) = (x + 2)(x - 5)(x + 6), derived from the zero-product property.
Explanation:To find a cubic function with the given zeros of -2, 5, and -6, we can use a formula associated with the zero-product property. This property states that if a product of factors equals zero, then at least one of the factors has to be equal to zero. So if -2, 5, and -6 are the zeros of the function, the factors of the function would be (x + 2), (x - 5), and (x + 6).
The cubic function f(x) is then derived from the multiplication of these factors. Therefore the cubic function with the zeros -2, 5, and -6 will be f(x) = (x + 2)(x - 5)(x + 6).
