Answer:

$x^{2} +11x-10$

Step-by-step explanation:

$(13x^{2} +9x-4)-(12x^{2} -2x+6)$

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

$13x^{2} +9x-4-12x^{2} +2x-6$

Rearrange in the highest order

$13x^{2} -12x^{2} +9x+2x-4-6$

Simplify

$x^{2} +11x-10$

Two beach rental companies compared their sales from last weekend. Both companies rent out jet skis and kayaks, and they charge

nignag [31]

Answer:

To rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20

Step-by-step explanation:

Since both shops charge the same amount for each kind of vehicle, we will assign variables to the their cost. The cost of a jet ski will be "x" and the cost of the kayak will be "y". Therefore we can create a system of equations as shown below:

Will's shop:

12*x + 9*y = 780

Fun Rentals:

7*x + 11*y = 570

$\left \{ {{12x+ 9y=780} \atop {7x + 11y =570}} \right.\\$

We can isolate "x" on the second equation, we have:

$x = \frac{570 - 11y}{7}$

Applying this value on the first equation:

$12[\frac{570 - 11y}{7}] + 9y = 780\\\frac{6840 - 132y}{7} + 9y = 780\\\frac{6840 - 132y + 63y}{7} = 780\\ 6840 - 132y + 63y = 5460\\6840 - 69y = 5460\\69y = 1380\\y = 20$
