Answer:
2R^2 + 21R - 36
Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms
Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
= 2R^2 + 24R - 3R - 36
= 2R^2 + 21R - 36
Hope this helps :)

-3y + 14 + y = 12
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms [Addition]: -2y + 14 = 12
- [Subtraction Property of Equality] Subtract 14 on both sides: -2y = -2
- [Division Property of Equality] Divide -2 on both sides: y = 1
Sold 17 tulips and 76 roses. tulips is equal to x and roses are equal to 4x+8. Then multiply by the amount they cost and then tulips are 2x and roses are 20x+40. They add together to get 414. 2x=20x=40=414. Solve. x=17. X is equal to the amount of tulips.
