The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!

Given the expression
We can rewrite the expression as:
The number line showing the location of the two numbers is attached below. Therefore:
Lentgh * width = area so, 3.5*9 right?
