Answer:
[tex](x - y)(x + y + 1)[/tex]
Step-by-step explanation:
[tex]x(x + 1) - y(y + 1)[/tex]
[tex]=> x^{2} + x - y^{2} - y[/tex]
Lets re-arrange it.
[tex]=> x^{2} - y^{2} + x - y[/tex]
Now , lets expand x² - y².
[tex]=> (x + y)(x - y) + (x - y)[/tex]
Taking ( x - y ) common ,
[tex]=> (x - y)(x + y + 1)[/tex]
Answer:
[tex]x(x + 1) - y(y + 1) \\ → {x}^{2} + x - {y}^{2} - y \\→( {x}^{2}- {y}^{2}) + (x - y) \\→ (x - y)(x + y) + (x - y) \\→ \boxed{ (x - y)(x + y + 1)}✓[/tex]
(x-y)(x+y+1) is the right answer.Leslie and Marvin, both teachers, are adding books to their class libraries. Leslie's classroom started out with a collection of only 20 books, but she plans to purchase an additional 3 books per week. Marvin's library started out with 40 books, and he has enough money in his budget to purchase another 1 book per week. At some point, the two teachers' libraries will contain the same number of books. How many weeks will that take?
Answer:
10 weeks
Step-by-step explanation:
L = 20 + 3x
M = 40 + x
20 + 3x = 40 + x
3x = 20 + x
2x = 20
x = 10
Point D is on line segment \overline{CE}
CE
. Given DE=x+10,DE=x+10, CD=6,CD=6, and CE=3x,CE=3x, determine the numerical length of \overline{DE}.
DE
.
Answer:
DE = 18
Step-by-step explanation:
Given that,
Point D is on line segment CE.
DE = x+10, CD=6 and CE=3x
We need to find the length of DE.
ATQ,
CE = CD + DE
Putting all the values,
3x = 6 + x+10
Taking like terms together
3x-x = 16
2x = 16
x = 8
DE = x+10
= 8+10
= 18
Hence, the length of DE is 18.

circumference/diameter = 3.14159
Which will solve the equation 12 = n
— ?
9
A Add 12 to both sides.
B Add 9 to both sides.
© Multiply both sides by 12.
D Multiply both sides by 9.
Answer:
Step-by-step explanation:
12=12n
We move all terms to the left:
12-(12n)=0
We move all terms containing n to the left, all other terms to the right
-12n=-12
n=-12/-12
n=1

You roll a red-sided die and a white-sided die. Find the probability. P(red is less than 3 and white is less than 3) Simplify the answer.
Answer:
1 on 3
Step-by-step explanation:
The red dice has 6 faces. The number you have to obtain is less than 3. So your answers must be 1 and 2. The numbers 1 and 2 are two solutions out of six. Now the same goes with the white dice. Two solutions out of six. You combine them and obtain 4 on 12. Then, you reduce the answer in minimal terms and finally obtain 1 on 3.
Make w the subject of aw-x=3w+2
Answer:
w = x+2/a−3
Step-by-step explanation:
Let's solve for w
aw−x=3w+2
Step 1: Add -3w to both sides
aw−x+−3w=3w+2+−3w
aw−3w−x=2
Step 2: Add x to both sides
aw−3w−x+x=2+x
aw−3w=x+2
Step 3: Factor out variable w
w(a−3)=x+2
Step 4: Divide both sides by a-3
w(a−3)/a−3 = x+2/a−3
w = x+2/a−3
The value of w is (2+x)/ (a-3).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
aw-x=3w+2
Now, solving for w
aw - 3w = 2 + x
w(a-3 )= 2+x
w= (2+x)/ (a-3).
Hence, the value of w is (2+x)/ (a-3).

Step-by-step explanation:
Area of a Rectangle
Given a rectangle of width W and length L, its area can be calculated with the formula:
A = WL
We are given the length of a rectangle is L=x and the width is W=x+10, thus the area is:

Hi there!
I provided a graph below to help you see how the domain is x ≥ 0
Since the function starts on point (0, -4) so we know th domian can equal zero. If you look at the graph, the function continuses infinitely after 0, so the domain of the function can be equal to or greater than zero.

Identify the x and y intercepts from the give equation: 5x – 2y = 10
Answer:
x-intercept : (2, 0)
y-intercept : (0, -5)
Step-by-step explanation:
The x-intercept is where y = 0, and the y-intercept is where x = 0. To find the intercepts, substitute a zero in for the other variable, and solve.
So the x-intercept of 5x – 2y = 10 is
5x – 2y = 10 → 5x – 2(0) = 10 → 5x = 10 →
x = 2 → (2, 0).
So the y-intercept of 5x – 2y = 10 is
5x – 2y = 10 → 5(0) – 2y = 10 → -2y = 10 →
y = -5 → (0, -5).
