Answer:

9x^2 - 24x + 16 is area in terms of x alternativly (3x-4)^2 is also true

Step-by-step explanation:

L * W = area length = width on a sqare so L * L = area too

(3x - 4) * (3x - 4)

use foil method

Answer:

9x^2 − 24x + 16

Step-by-step explanation:

To find the area of a square, you use the formula

A = x^2

So we plug in 3x-4 for x

A = (3x-4)^2

A = 9x^2 − 24x + 16

Hans the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the ot

xz_007 [3.2K]

A = hours for plan A
B = hours for plan B

Monday: 6A + 5B = 7
Tuesday: 2A + 3B = 3

use elimination by multiplying the 2nd equation by 3.

Doing that we get 3(2A + 3B = 3) = 6A + 9B = 9

So the two equations are now:
6A + 9B = 9

6A + 5B = 7

Subtract and we have 4B = 2

B = 2/4 = 1/2 of an hour

Now put 1/2 back into either equation to solve for A

6A + 5(1/2) = 7
6A + 5/2 = 7
6A = 14/2 -5/2
6A = 9/2
divide by 6 to get A = 9/12 = ¾ hours

Plan A = 3/4 hour

Plan B = 1/2 hour

What is the length of a radius of the circle represented by the equation below?

MakcuM [25]

Answer:

Step-by-step explanation:

Given the circle: $x^2 + y^2 - 4x - 4y + 4 = 0$

To determine the length of the radius, we complete the square.

Step 1: Subtract 4 from both sides

$x^2 + y^2 - 4x - 4y + 4 -4= 0-4\\x^2 + y^2 - 4x - 4y = -4$

Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides

$x^2 - 4x+(-2)^2+ y^2 - 4y+(-2)^2 = -4+(-2)^2+(-2)^2$

Step 3: Factorize the Left Hand side and simplify the Right Hand side.

$(x-2)^2+ (y-2)^2 = 2^2$

Comparing with the standard form of the equation of a circle

$(x-h)^2+ (y-k)^2 = r^2$

r=2

Therefore, the radius of the circle is 2.
