Answer:
12x^3 - 11x^2 + 9x + 18
Step-by-step explanation:
12x^3 - 20x^2 + 24x + 9x^2 -15x + 18
Combine like terms
12x^3 - 11x^2 + 9x + 18
The length of the base is 6. You can use the formula b=a/h to find the base. <span />
An expression is defined as a set of numbers, variables, and mathematical operations. The value of x for which the expression (x-1)(x-7)=0 is 1 and 7.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
For the given expression, (x-1)(x-7), the value of x for which the expression will be equal to 0 can be found by equation the factors of the expression to 0. Therefore,
x-1 = 0
x = 1
and
x-7=0
x = 7
Hence, the value of x for which the expression (x-1)(x-7)=0 is 1 and 7.

For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer
Answer:
x ≈ 1.28
Step-by-step explanation:
I just took the exam:
Area of rectangle =(3x-1)(x+6), Area of circle = PI(x+1)^2. If you graph these and find where they intersect, you will get x ≈ 1.28.
I hope this helped! :)
