CORRECT ANSWER: It decreased by 40%
CORRECT SOLUTION:
1. Divide the 42 by 105 (make sure you divide the after amount before the actual amount)
2. The answer you get is 0.4
3. move decimal point 2 places to the right and you get your answer
Hope this helps :)
Answer:
(3x − 2) (x + 2)
Step-by-step explanation:
For a quadratic ax² + bx + c, you can factor using the AC method.
1. First, multiply a and c.
2. Next, find factors of ac that add up to b.
3. Divide the factors by a. Reduce if possible.
4. The numerator of the fraction becomes the constant. The denominator of the fraction becomes the coefficient.
3x² + 4x − 4
In this case, a = 3, b = 4, and c = -4.
1. 3 × -4 = -12
2. Factors of -12 that add up to 4 are -2 and +6
3. Divide by 3 and reduce: -2/3, 6/3 = 2/1
4. The factors are 3x − 2 and x + 2
3x² + 4x − 4 = (3x − 2) (x + 2)

Hey there!
On this problem, we have to combine like terms. A like term in this sense doesn't have to have the same coefficient, but it has to have the same variable.
Our like terms are 2m and 4m, along with 3 and 5.
When we add 2m and 4m we get 6m, and when we add 5 and 3 we get eight.
Notice how 5 and three are like terms because they're both whole numbers and don't have any variables.
Your solution is 6m + 8.
My advice to you is pay attention to your like terms and don't mix them up. A strategy is to underline like terms in the same color.
Hope this helps!
