Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out

What is the remainder when 7x^2- x^3is divided by x - 8?
Answer:
The remainder is -64
Step-by-step explanation:
Given
[tex]7x^2 - x^3[/tex]
Divided by [tex]x - 8[/tex]
Required
Determine the remainder
Equate [tex]x - 8[/tex] to 0
[tex]x - 8 = 0[/tex]
Solve for x
[tex]x = 8[/tex]
Using remainder theorem, substitute 8 for x in [tex]7x^2 - x^3[/tex]
So, we have:
[tex]7 * 8^2 - 8^3[/tex]
Evaluate all exponents

Answer:
x² +15x +56
Step-by-step explanation:
We presume these are dimensions of a rectangle, so the area is their product.
A = (x +8)(x +7) = x(x +7) +8(x +7) = x² +7x +8x +56
A = x² +15x +56

Two rules for creating a pattern are given below. Each rule begins with a number called the input and creates a number called the output.
Rule 1: Subtract 8 from the input to get the output.
Rule 2: Divide the input by 3 to get the output.
Which input and output table works for both rules?
Choose 1 answer:
(Choice A)
Input Output
18 6
(Choice B)
Input Output
12 4
(Choice C)
Input Output
16 8
Answer:
None of the above
Step-by-step explanation:
Because when you subtract 8 and divide by 3 any on these inputs, none of them result in the output.
An arm wrestler is the champion for a period of 75 hours. (Here, by an hour, we mean a period starting from an exact hour, such as 1 P.M., until the next hour.) The arm wrestler had at least one match an hour, but no more than 125 total matches. Show that there is a period of consecutive hours during which the arm wrestler had exactly 24 matches.
Answer:
The answer is "In the i-th to J-th hour, the Wrestler played only 24 match-ups".
Step-by-step explanation:
Let [tex]x_i[/tex] label the number of teams played by the wrestler for [tex]1 \leq i \leq 75[/tex], after i-th hour, where [tex]1 \leq x_i \leq 125[/tex]. This also means [tex]25 \leq x_i + 24 \leq 149[/tex]. The Pigeonhole Principle means that [tex]\ni i \neq j \ni x i+ 24 = x ,j[/tex] is played exactly 24 matches between the i-th and j-th-hours end. Thus, 150 integrals [tex]x_1,x_2,......x_{75}, x_1+24,x_2+24.[/tex] In the i-th to J-th hour, the Wrestler played only 24 match-ups.

Create a factorable polynomial with a GCF of 6. Rewrite that polynomial in two other equivalent forms. Explain how each form was created.
Answer:
Answer: the equivalent form of 6(2x+3x+10) are 12x+18x + 60 and 30x+60.
Hope this helps
Answer:
The equivalent form of 6(2x+3x+10) is 12x+18x + 60 and 30x+60.
Explanation:
12x+18x + 60 is one of the equivalent form of 6(2x+3x+10) To get another equivalent form we combine like terms.
30x + 60 is the equivalent form of 6(2x+3x+10)
4x + 3/2x +9 solve for x
Solve by completing the square:
x^2 + 3x - 9 = 0
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
Answer:
2 solutions. x = -3/2 + 3/2 * sqrt(5) and x = -3/2 + -3/2 * sqrt(5)
Step-by-step explanation:
Let's solve your equation step by step.x^2 + 3x −9 = 0
For this equation: a=1, b=3, c=-9
1x^2 + 3x+ −9 = 0
Step 1: Use quadratic formula with a=1, b=3, c=-9.
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex])/2a
x = (-3 ± [tex]\sqrt{3^2 - 4(1)(-9)}[/tex])/2a
x = (-3 ± [tex]\sqrt{45}[/tex])/2
x = -3/2 + 3/2 * sqrt(5) or x = -3/2 + -3/2 * sqrt(5)

y=-0.0241x^2+x+5.5

A rectangular carport has area of one 50 ft.The width of the carport is 5 feet less than twice its length. Find the length and width of the carport
Width= ? feet,
Length= ? feet
Answer:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]
Step-by-step explanation:
Given
[tex]W= Width\\ L = Length[/tex]
[tex]Area = 150[/tex]
[tex]W=2*L- 5[/tex]
Required
Determine the dimension
Area is calculated as:
[tex]Area = L * W[/tex]
So, we have:
[tex]L * W = 150[/tex]
Substitute: [tex]W=2*L- 5[/tex]
[tex]L * (2*L-5) = 150[/tex]
[tex]L * (2L-5) = 150[/tex]
Open bracket
[tex]2L^2 - 5L = 150[/tex]
Rewrite as:
[tex]2L^2 - 5L - 150=0[/tex]
Expand
[tex]2L^2 -20L + 15L - 150 = 0[/tex]
Factorize:
[tex]2L(L -10) + 15(L - 10) = 0[/tex]
[tex](2L + 15) (L - 10) = 0[/tex]
Split
[tex]2L + 15=0[/tex] or [tex]L -10 = 0[/tex]
Solve for L
[tex]2L =-15[/tex] or [tex]L = 10[/tex]
L cannot be negative
So:
[tex]L = 10[/tex]
Substitute [tex]L = 10[/tex] in [tex]W=2*L- 5[/tex]
[tex]W = 2 * 10 - 5[/tex]
[tex]W = 20 - 5[/tex]
[tex]W = 15[/tex]
Hence:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]

A pyramid has a regular hexagonal base with side lengths of 4 and a slant height of 6. Find the total area of the pyramid.
9514 1404 393
Answer:
113.57 square units
Step-by-step explanation:
The area of each of the 6 triangular faces is ...
A = 1/2bh
A = (1/2)(4)(6) = 12 . . . . square units
The area of the base is ...
A = (3√3)/2·s² . . . . . . for side length s
A = (3√3)/2×4² = 24√3 . . . . square units
Then the total area is ...
total area = base area + face area
= 24√3 + 6(12) = 24(3 +√3) ≈ 113.57 . . . square units
