Answer:
No Solution.
Step-by-step explanation:
2 - 3(x + 4) = 3(3 - x)
2 - 3x - 12 = 9 - 3x
Move the terms in x to one side and the numbers to the other
-3x + 3x = 9 - 2 + 12
0 = 19.
This is absurd so there is No Solution.

Step-by-step explanation:
Three half live
1/2 * 1/2 * 1/2 = (1/2)³ = 1/8
There would be 1/8 of the original amount left
185 * 1/8 = 23.125
Rounded
25 grams
Answer:
2(x + 2)² - 5
Step-by-step explanation:
Given
2x² + 8x + 3
To obtain the required form use the method of completing the square.
The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x
= 2(x² + 4x) + 3
add/subtract ( half the coefficient of the x- term)² to x² + 4x
= 2(x² + 2(2)x + 4 - 4) + 3
= 2(x + 2)² - 8 + 3
= 2(x + 2)² - 5
with p = 2 and q = - 5
