I might be wrong but I say 16
Answer:
<h2>
7x+6</h2>
Step-by-step explanation:
Aryana simplified the expression 3(x + 4) + 2(2x – 3). She justified her work by letting x = 3 in both the given and simplified expressions. Which is the correct simplified expression for Aryana's expression? What is the result for both expressions when x = 3?
Simplified Expression:
3(x + 4) + 2(2x – 3)
3x+12+2(2x-3)
3x+12+4x-6
7x+6
5x − 2y = − 16 | x 4
4x − 5y = − 23 | x 5
20x - 8y - 20x + 25 y = - 64 - (- 115)
25y - 8y = 115 - 64
17y = 51
y = 51 : 17
y = 3
5x - 2×3 = - 16
5x - 6 = - 16
5x = - 16 + 6
5x = - 10
x = - 10 : 5
x = - 2
Step-by-step explanation:
(5b - 2c)*(2a - 3c) = 5b*2a - 3c*5b - 2a*2c + 6c^2
