Answer: Multiplication
Step-by-step explanation:
Hope this helps :)
Answer:
Because it's taken out of context, I am not completely certain, but I'm pretty sure it's just another way to write the multiplication symbol. A lot of people like it because it's faster to write, and you won't confuse it with the variable x.
Hope this is helpful to you!

express x^2 -8x+5 in the form (x-a)^2 -b where a and b are integers
Answer:
(x - 4)² - 11
Step-by-step explanation:
Given
x² - 8x + 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
= x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11

AnsThe median for Set A is greater than the median for Set B.
Step-by-step explanation:
Help please. Solve the system of equations using substitution. Show your work in the workspace provided below.
y=3x - 11
O=6x-2y-22
Answer:
x=0 y=-11 (0,-11)
Step-by-step explanation:
1. take what y equals (3x-11) and plug it in for y in the second equation
Should look like this: O= 6x-2(3x-11)-22
2. Then distribute O=6x-6x+22-22
3. Then combine like terms O= 0 the 22's cancel out as well as the x's
x= 0
4. plug 0 in for x in the first equation y=3(0)-11
5. y= -11
6. x=0 y=-11 (0,-11)
solve for x. please?

where do the numbers go and explain how you decided where to place the numbers
Answer:
Between 0 and 1 goes 1/4 then after that is 5/8 then between the 1 and the 2 put 1 and 3/8/
Step-by-step explanation:
The reason for this is simply smallest to biggest. Which is bigger 1/4 or 5/8? Well if you want you can put it into a decimal: 1/4 = 0.25 and 5/8 equals 0.625. So 0.25 is closer to 1 and then 5/8 is the next closest to 1 but it is closer to 2. And lastly 1 and 3/8 is more then 0 and it's more then 1 so it goes in between 1 and 2 This is how it goes: 0 1/4 5/8 1 1 and 3/8 2
HOPE THIS HELPS

Find The Surface Area
multiply: (x+a)^2-(x-b)^2+x^2+(a-b)x-ab by (a+b)
Answer:
Step-by-step explanation:
Step-by-step explanation:the answer is =−a2b2y−ab3y+a2+3ax−b2+bx+x2 how did i get answer:Distribute:
=a2+2ax+x2+−b2+2bx+−x2+x2+(a)(x)+(−b)(x)+−a2b2y+−ab3y
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
Combine Like Terms:
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
=(−a2b2y)+(−ab3y)+(a2)+(2ax+ax)+(−b2)+(2bx+−bx)+(x2+−x2+x2)
=−a2b2y+−ab3y+a2+3ax+−b2+bx+x2

What is the area of the picture?
What is the area of the board?
What are the dimensions of the board?
9514 1404 393
Answer:
picture: 324 square cmboard: 1296 square cmboard dimensions: 36 cm squareStep-by-step explanation:
a) The area of the picture is the product of its dimensions:
(18 cm)² = 324 cm²
__
b) The area of the board is 4 times that:
board area = 4×324 cm² = 1296 cm²
__
c) The dimensions of the square board are the square root of its area:
√1296 = √(4×324) = (√4)(√324) = 2×18 = 36 . . . . cm
The board is 36 cm square.

The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for
$2200 is worth $1540 after 6 years.
The linear function V(x) that expresses the value of the computer as a function of the age (x) in years is V(x)= type your answer_
The value of the computer after 8 years is $ type your answer...
After type your answer.
years the computer will be worth nothing.
Answer:
v(x)=2200-N*110
the value of computer after 8 years is 1320
Step-by-step explanation:
at 0 years the value is 2200
after 6 years the value is 1540
we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110
where n is number of years
so after 8 years : v(8)=2200-8*110=1320$

What is the surface area of the square pyramid represented by the net below?
A: 48 cm
B: 96 cm
C: 64 cm
D: 112 cm
Answer: C: 64 cm
Step-by-step explanation:
The square has a a side of 4 centimeter meaning the area would be 16 cm. The area of the triangle is determined by half of the area of the base times the height. This mean that 4 x 6 = 24 and then 24/2 = 12. 4 x 12 = 48 (due to four triangles). 48 + 16 = 64. It is C: 64 cm
