Let's split this up to make it easier.

Let's expand 5(2x - 1) first.

<u>Multiply </u>5 by 2x and - 1

5 × 2x = 10x

5 × -1 = -5

Now we have 10x - 5

Let'd do the other side

<u>Multiply </u>2 by 3x and -6

2 × 3x = 6x

2 × -6 = -12

Now we have 6x - 12

Let's combine both sides now.

<em>(10x - 5) + (6x - 12) </em>

Combine like terms:

10x + 6x = 16x

-5 + -12 = -17

Your final answer is 16x - 17

Hope I helped! Message me if you have any questions

Which of the following is equivalent to the expression (9x^2y^3)(12x^-3y^5)( 2xy)? 23x^-5y^8 216^9 -x^-6y^8
Lubov Fominskaja [6]
If we multiply the first numbers in the three  parentheses we get 9*12*2  = 216
then  x's come to x to 1 and the y terms come to  y^9

so the answer is 216y^9

The equation for the circle below is the x2 + y2=81. what is the length of the circles radius
larisa [96]

Answer:

9

Step-by-step explanation:

Compare your x2 + y2=81 to the following:

                       x^2 + y^2 = 81

The " ^ " symbol indicates exponentiation.

Now compare  x^2 + y^2 = 81 to

                         x^2 + y^2 = r^2.  

This is the standard equation of a circle of radius r centered at the origin, (0,0).  You can see for yourself that 81 must equal r^2.


Taking the square root of 81, we get plus or minus 9.

But the radius must be positive, so we reject the -9 and take +9.

The radius is 9.

A town's recreation department is updating its parks. The parks must have slides and swings.
Fittoniya [83]
Number of swings = x
Number of slides = y

First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x

Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250

Based on this:
The correct choices are: b and d</span>
