german4 years ago
6 0

Since

x^2+4x+4=(x+2)^2

Is a perfect square, we can think of the "-6" at the end as a "+4-10" and we have

x^2+4x-6 = x^2+4x+4-10 = (x+2)^2-10

Which is the required form

A school paid $248 for new basketballs and soccer balls. The number of basketballs purchased was 6 less than 3 times the number
andreyandreev [35.5K]

Answer:

4 Soccer balls and 6 Basketballs

Step-by-step explanation:

You can solve this problem by setting up a system of equations. Letting x be Soccer balls and y be Basketballs. Remember, Money goes with, Money goes with Money, meaning that for this problem the first equation that can be made is $248 = $28y + $20x with Y being basketballs and x being soccerballs. Next is a little more difficult. You will be creating the equation y=3x-6 because it is 6 less than 3 times the amount of x or Soccer balls. From here you can plug in the equations into a graphing calculator and graph it and see where the two lines intersect. This would be at (4, 6). When I said to let x equal Soccer Balls and y equal basketballs that is where I got the 4 soccer balls and 6 basketballs.

Place these numbers in correct order and and simplify 25x^2 +6x^3 -7 +17 -24x^4 +6
Ket [755]

Answer:

-24x^4+6x^3+25x^2+16

Step 1:

We need to place the numbers in descending order of the power. Here, -24x^4 has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.

-24x^4+6x^3+25x^2+17-7+6

Step 2:

We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.

17-7=10\\10+6=16

Our final equation:

-24x^4+6x^3+25x^2+16
