The value of x is √2.5
<h3>How to solve arithmetic?</h3>
Arithmetic can be solved by using PEMDAS rule.
P = parenthesis
E = exponential
M = Multiplication
D = division
A = addition
S = Subtraction
Therefore,
12 - 4 + 5x² = 20
12 - 4 + 5x² = 20
8 + 5x² = 20
5x² = 20 - 8
5x² = 12
x² = 12 / 5
x = √2.4

The reactangle has an area of x.
So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are <u />a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:




y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.And so if the dimension is 5 by 8.
Then the area is

And so then

And then after the dilation, it would be

We could check it another way too. Since we said the scale factor is 3, then:

So
basically
15 by 24 is the new dimensions :)
Answer:
77
Step-by-step explanation:
Plug in:
F(4) = (4)3 + 2(4)2 + 1
F(4) = 12 + (8)^2 + 1
F(4) = 12 + 64 + 1
F(4) = 77
(assuming 2x2 = 2x squared)
There is no solution it’s in final form
