Step-by-step explanation:
Given expression is
To simplify the given expression in two ways:
First way:
Given
Multiplying 3 on both sides
(adding the like terms)
Dividing by 3 on both sides
Therefore the given expression is solved that
Another way:
Given
(adding the like terms)
Therefore the given expression is solved that
In the two different ways we have solved the given equation as
Answer:
f(x) = 5x^3 - 9x^2 + 245x - 441.
Step-by-step explanation:
Complex zeros are in conjugate pairs so the third zero is -7i.
In factor form we have:
f(x) = (x - 7i)(x + 7i)(5x - 9)
= (x^2 - 49i)^2)(5x - 9)
= (x^2 + 49)(5x - 9)
= 5x^3 - 9x^2 + 245x - 441.

Answer:
Set the area equal to x2, solve for x, and then multiply the value of x by 4.
Step-by-step explanation:
The area of the picture is given by
A = s^2 where s is the side length
Let the side length be x
A = x^2
Take the square root of each side
sqrt(A) = sqrt(x^2)
x = sqrt(A)
We want to find the perimeter since we are framing the border
P = 4s since the picture is a square
P = 4 * x
