What should be the first step to solve the equation? 2x + 9(x - 1) = 8(2x + 2) - 5

A. Combine like terms on each side of the equation.

B. Use the distributive property on each side of the equation.

C. Use the subtraction property of equality to subtract 5 from each side of the equation.

D. Use the addition property of equality to add 2x to each side of the equation.

B.

Step-by-step explanation:

You will need to get rid of the parenthesis to make the problem easier for you to work with. Since there is a number in front of the parenthesis, you will need to distribute that to both numbers in the parenthesis.

For this example, you would multiply the 9 to both the x and -1, and then 8 to both 2x and 2.

think about it deeply and passionately about this property

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
