the answer is A i think
Step-by-step explanation:
look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]

Please solve and show your work! <3 have a great day!
12x-18y*-90
Simplifying
12x + -18 = 90
Reorder the terms:
-18 + 12x = 90
Solving
-18 + 12x = 90
Solving for variable 'x'.
████████████████████████████████████████████
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 12x = 90 + 18
Combine like terms:
-18 + 18 = 0
0 + 12x = 90 + 18
12x = 90 + 18
Combine like terms:
90 + 18 = 108
12x = 108
Divide each side by '12'.
x = 9
Hence,
x = 9

Answer:
2) M(2, -4), N(-2, 4)
Step-by-step explanation:
Point L is at (-2, -4). When it is reflected across the y-axis, the x value will turn into its opposite. This means point M is at (2, -4). This same logic applies to reflecting across the x-axis only this time the y value will turn into its opposite. Therefore, point N is at (-2, 4).

Hunter bought a cell phone for $159 and 6% sale tax was added at the register. Hunter gave the cashier nine $20 bills, how much change should he receive?
Answer:
Step-by-step explanation:
So in order to solve this you would multiply 159 by 6% and get 9.54 so therefore you add the 9.54 to 159 and get 168.24 Then you add together all the bills which is 180 and subtract 180- 168.24 which equals 11.76 so the answer to your question is that Hunter shall received $11.76 in change.
Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds 150% markup to the total price she paid for the shirt (including the cost of shipping).

Answer: 4.18$ or 4.19$ per shirt (I’m not entirely sure my answer is correct but do what you must with this info)
Step-by-step explanation: 200 times 2.80 is 560,
5% of 560 is 588,
150% of 588 is 882,
and then 882 divided by 200 is 4.18 (or 4.19)

Click to show whether each equation represents a linear or nonlinear function.
Answer:
[tex]y = x^2 + 1[/tex] -- Nonlinear
[tex]y = x^1 + 2[/tex] -- Linear
[tex]y = x[/tex] --- Linear
[tex]y = 5(x + 2)[/tex] --- Linear
[tex]y = x(x)[/tex] --- Nonlinear
Step-by-step explanation:
Required
Categorize each function as linear or nonlinear
First, it should be noted that a linear function has the form [tex]y = mx + b[/tex].
So, the following question will be solved based on the above form
(a):
[tex]y = x^2 + 1[/tex]
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
(b):
[tex]y = x^1 + 2[/tex]
This can be further expressed as:
[tex]y = x + 2[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(c):
[tex]y = x[/tex]
This can be further expressed as:
[tex]y = x + 0[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(d):
[tex]y = 5(x + 2)[/tex]
This can be further expressed as:
[tex]y = 5x + 10[/tex] -- by opening the bracket
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(e):
[tex]y = x(x)[/tex]
This can be further expressed as:
[tex]y = x^2[/tex] --- by opening the bracket
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
