Answer:

$\boxed{x^2-2x+1}$

Step-by-step explanation:

$(x-1)(x-1)$

Apply FOIL Method.

$x(x-1)-1(x-1)$

$x^2-x-x+1$

Combine like terms.

$x^2-2x+1$

Answer:

$x^2-2x+1$

Step-by-step explanation:

=> (x-1)(x-1)

Using FOIL

=> $x^2-x-x+1$

=> $x^2-2x+1$

Solve equation: -3|d-5|=-6

gulaghasi [49]

Answer:

d = 7, 3

Step-by-step explanation:

First, you need to isolate the absolute value

-3|d - 5| = -6

divide both sides by -3:

|d - 5| = 2

break into 2 equations:

d - 5 = 2, d - 5 = -2

solve both equations and collect solutions:

d = 5 + 2, d = 5 - 2

d = 7, 3

For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.

xz_007 [3.2K]

For the function
f(x) = 4^(x-1) +2
the average rate of change on the interval [1, 2] is found by computing
(f(2) - f(1))/(2 - 1)
= ((4^1+2) - (4^0+2)/1
= (6-3)
= 3

We are interested in the dimensions of a certain square a rectangle had length triple the side of this square and width two unit

Sphinxa [80]

Let s be the side length of the square. The dimensions of the rectangle are three times the side of the square (i.e. 3s), and two less than the side of the square (i.e. s-2).

So, the area of this rectangle is

$3s(s-2)=3s^2-6s$

The area of the square is $s^2$ , and we know that the two areas are the same, so we have

$3s^2-6s=s^2 \iff 2s^2-6s=0 \iff 2s(s-3)=0 \iff s=0 \lor s=3$

The solution s=0 would lead to the extreme case where the rectangle and the square are actually a point, so we accept the solution s=3.
