Answer: True

Step-by-step explanation:

Suppose the length and width of the original rectangle is L and W

After dilation by a factor of y, it becomes yL and yW

Area of the original rectangle A_1=L\times W

The area of the dilated rectangle is A_2=yL\times yW=y^2LW

we can see that

\Rightarrow A_2=y^2A_1

Comparing with the original expression, the value that will go into the green box is 5

<h3>Exponents and indices</h3>

Given the indices expression below;

\frac{4^{-5}}{4^4}

Since 4^-5 is equivalent to 1/4^5, hence the given expression will be equivalent to;

\frac{1}{4^5\times4^4}

Comparing with the original expression, the value that will go into the green box is 5

stira [4]
The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130

In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110

How do you write polynomials in standard form
andre [41]
You put the highest exponent power first, then you go down until you reach a regular number (a number with a variable goes before a normal number)

Ex: 5x^3+2x^2+4x+5
