x^2 -14x+49
Step-by-step explanation:
(x-7) ^2
(x-7)(x-7)
FOIL
first ( x*x) = x^2
outer -7x
inner -7x
last -7*-7 = 49
Add these together

Is there a difference between 6.780 and 6.78? Why or why not?
Answer:
Step-by-step explanation:
No there is no difference because in a decimal the zero's don't matter, they can go on infinitely but if the numbers above zero are the same and in the same order then the zero's don't make any difference.
Given m||n, find the value of x.
(9x-5)(6x+20)
Answer:
5/9 & -10/3
Step-by-step explanation:
Set each to 0 and solve:
9x-5 = 0
9x=5
x=5/9
6x+20=0
6x=-20
x=-20/6
x= -10/3 or -3 1/3
In the figure, since the line m and line n are parallel, the value of x is 25/3.
We have,
From the figure,
The two angles are corresponding angles since line m and line n are parallel.
Now,
9x - 5 = 6x + 20
Combine like terms on one side.
9x - 6x = 20 + 5
3x = 25
Divide 5 on both sides.
3x/3 = 25/3
x = 25/3
Thus,
The value of x in the given figure is 25/3.

A donut shop made 12 dozen donuts to give to a school’s math club.
Which expression represents how many donuts each student would get if the donuts were equally distributed and there were x
x
students in math club’s
Answer:
Number of donuts each student get = 144 / x
Step-by-step explanation:
Given:
Number of donuts = 12 dozen
Number of students = x
Find:
How many donuts each student get
Computation:
Total number of donuts = 12 × 12 = 144
Number of donuts each student get = Total number of donuts / Number of students
Number of donuts each student get = 144 / x

A rectangular vegetable patch has a perimeter of 36 meters and an area of 80 square meters. What are the dimensions of the vegetable patch?
Answer: 5 and 4
Step-by-step explanation:
Perimeter = 2 ( L + W)
18 = 2(L + W) divide through by 2
9 = L + W
9 - L = W
Area = L * W
20 = L (9 - L)
20 = 9L - L^2
L^2 - 9L + 20 = 0 factor
(L - 5) (L - 4) = 0
Set both factors to 0 and solve for L
L = 5 and L = 4

Subtract the following fractions. (Reduce answers to lowest terms.)
3/10 - 1/4=
3/14
3/6
1/2
1/20
Answer:
1/20
Step-by-step explanation:
3/10 - 1/4
First, convert the fractions to a common denominator:
3/10 *2/2 = 6/20
1/4 * 5/5 = 5/20
Now put them back into the equation and solve:
6/20 - 5/20 = 1/20
Another way to do this:
3/10 - 1/4
Convert the fractions into decimals:
3/10 = 0.3
1/4 = 0.25
substitute back into the equation and solve:
0.3 - 0.25 = 0.05
convert back into fractions:
0.05 = 1/20
what is the value of x ?
Step-by-step explanation:
2(2x - 6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26
4x + 2x -12 + 6 = 26
6x - 6 = 26
6x = 26 + 6
6x = 32
x =32/6
x = 5.3333
Answer:
Step-by-step explanation:
2(2x -6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26

Answer:a. v
Step-by-step explanation:
Given
Required
Identify the variable
Literary, variable means things that change in values;
Going by this definition, we have that:
3 -> This is not a variable because its value will always be 3
v -> This is a variable because its value can change once its value changes, the result of the expression will also change
- -> This is not a variable; it is an arithmetic operator to subtract
8 -> This is not a variable because its value will always be 8
Take for instance
When
Notice that there's a difference in both results;
This is as a result of v being a variable

Answer:
Q7) ( 2,-2)
Q8) (- 0.5 , -2)
Step-by-step explanation:
As we have to find the mid-points of the line segments, the line segments will be divided in same ratio i.e. 1:1 (∵ A Mid-point divides a line segment into equal parts )
According to Section formula ,
[tex]( x' , y') = (\frac{mx^2 + nx^1}{m+n} , \frac{my^2+ny^1}{m+n} )[/tex]
where (m,n) are the ratios in which a line segment is divided & ( x¹ , y¹ ) ( x², y²) are the co-ordinates of a line segment.
In Q7 ,
x¹ = 3 , y¹ = -9 , x² = 1 , y² = 5 & m = n = 1
So putting the section formula here gives :-
[tex]( x' , y') = (\frac{1*1 + 1*3}{1+1} , \frac{1*5+1*(-9)}{1+1} ) = ( 2 , -2)[/tex]
In Q8 ,
x¹ = 5 , y¹ = -1 , x² = -6 , y² = -3
So putting the section formula here gives :-
[tex](x' , y') = (\frac{1*(-6) + 1*5}{1+1} , \frac{1*(-3) + 1*(-1)}{1+1}) = ( -0.5 , -2)[/tex]
