Answer:

side of square is 2-x

Step-by-step explanation:

Area of the square is side * side or side ², so the expression for the side has to be square root of area

A = 4 -4x + x²

It should be recognized that 4 -4x + x²is a special product ( 2-x)² because this is a perfect square trinomial

side of square is 2-x

What is the answer to x^2-11=25 please

Westkost [7]

Hey there!

$\mathsf{x^2 - 11 = 25}$

$\large\textsf{ADD 11 to BOTH SIDES}$

$\mathsf{x^2 - 11 + 11 = 25 + 11}$

$\large\textsf{CANCEL out: -11 + 11 because that gives you 0}$

$\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}$

$\mathsf{25 + 11 = \bf 36}$

$\large\textsf{NEW EQUATION: }\mathsf{x^2=36}$

$\large\textsf{Take the square root of the number (36)}$

$\mathsf{x = \pm \sqrt{36}}$

$\mathsf{\pm = \boxed{\bf plus-or-minus}}$

$\mathsf{x = \sqrt{-36}\rightarrow \bf -6}$

$\large\textsf{or}$

$\mathsf{x = \sqrt{36} = \bf 6}$

$\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

знайдіть розв'язок системи лінійних рівнянь 10x-6y = 18 9x+6y=39

Katen [24]

Answer:

(-21, -38)

Step-by-step explanation:

Given the simultaneous equation

10x-6y = 18 ... 1

9x+6y=39 ...2

Using the Elimination method

Subtract

10x - 9x = 18 - 39

x = -21

substitute x = -21 into 1;

From 1:

10x-6y = 18

10(-21)-6y = 18

-210 - 6y = 18

-6y = 18+210

-6y = 228

y = 228/-6

y =-38

Hence the solution to the system is (-21, -38)

A bicycle store costs $4200 per month to operate. The store pays an average of $75 per bike. The average selling price of each

Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

To find bike we need Algebra to solve the equation.
when x = 1 , Y = 135 *x
When x 2 , Y = 135 *2
Formula you could apply to go for break even y = 135*x
Bicycle store pays about $4200
Algebra used for every business and working to make easy task.
It takes about 31 bicycle a month to get into break even.
Every store needs break even to not incur lost.
Break even point is equilibrium between income and expenses.
