Answer:
10x² + 11x - 6
Step-by-step explanation:
The area (A) is the product of the sides, that is
A = (2x + 3)(5x - 2) ← expand using FOIL
= 10x² - 4x + 15x - 6 ← collect like terms
= 10x² + 11x - 6
Answer: 2676
Step-by-step explanation:
223 x 12 = 2676
This is because 223 12 times equals 2676.
*I will attach my work for the problem so you can see the solving process more clearly :).
Hope this helps :).
The system of equations becomes:
s + u = 28 This represent the number of candles sold
16s + 10u = 400 This represents the value of the candles sold
