What is the square root of 4

The measure of one side of a square is (s + 3) inches. Write two different expressions to express the perimeter of this square.

valkas [14]

4(s+3)
or it could be
(s+3) + (s+3) + (s+3) + (s+3)

find the perimeter (p) of a rectangle with a length (1) of 12m and a width (w) of 8.4m using the formula p=21+2w

NikAS [45]

Answer:

The answer is 40.8 m.

Step-by-step explanation:

To find the perimeter of the rectangle, use the formula P= 2( $l$ )+ 2( $w$ ). Plug in the information given in the question, and the equation will look like

P= 2(12m) + 2(8.4m)

Solve the equation, and the final answer will be 40.8 m.

Simplify the expression so there is only one positive power for each base.

katen-ka-za [31]

Answer:

Option (A)

Step-by-step explanation:

The given expression is,

$(5^{-2}\times 4^{-4})^{-2}$

Since $x^{-1}=\frac{1}{x}$ and $\frac{1}{x^{-1}}=x$

$5^{2}=\frac{1}{5^{-2}}$

$4^{2}=\frac{1}{4^{-2}}$

Therefore, $(5^{-2}\times 4^{-4})^{-2}=\frac{1}{(5^{-2}\times 4^{-4})^{2}}$

$=\frac{1}{(5^{-2})^2\times (4^{-4})^2}$

$=\frac{1}{5^{-4}\times 4^{-8}}$

$=\frac{1}{5^{-4}}\times \frac{1}{4^{-8}}$

$=5^{4}\times 4^{8}$

Option (A) will be the answer.

Find the slope of the line please help

Alex777 [14]

Answer:

m = -1/3

Step-by-step explanation:

There are two ways that you can use to get this answer.

The first way is to use the graph. You can see that to get from Point A to Point B, the dots go over 1 and down 3. For the fraction, you put the amount that you go to the side (1) over the amount you go down (3) to get 1/3. Since the points go down gradually, the slope is negative, so 1/3 becomes -1/3.

The second way is to take the two points, (1, 4) and (2, 1) and subtract them. First, subtract the x-coordinate from Point B from Point A to get -1. Then do the same thing with the y-coordinates to get 3. Put the -1 over 3 because x comes before y, and you have your slope.

I hope this helped :)

For two functions, a(x) and b(x), a statement is made that a(x) = b(x) at x = 2. What is definitely true about x = 2? (2 points)

Irina-Kira [14]

The statement that is definitely true about x = 2 is Both a(x) and b(x) have the same output value at x = 2.

<h3>How to find the statement that is true about the functions a(x) = b(x) at x = 2?</h3>

If we have two functions a(x) and b(x), a statement is made that a(x) = b(x) at x = a, this implies that the values of the functions a(x) and b(x) are equal at x = a.

Given that the two functions a(x) and b(x), a statement is made that a(x) = b(x) at x = 2.

Then the statement that is definitely true about x = 2 is Both a(x) and b(x) have the same output value at x = 2.

So, the statement that is definitely true about x = 2 is Both a(x) and b(x) have the same output value at x = 2.
