You use PEMDAS.
First, parentheses
(x+4) = 4x
(3x+5) = 3x+5
So, that is
4x*3x+5
Then, exponents. We don’t have any.
Then, multiplying.
4x*3x is 12x
So, 12x+5
And then, division. We don’t have anything to divide.
Then, addition and subtraction
You can’t add the variable to a number, so the answer is just
12x+5.
Hope it helped. :)
Answer:
The correct answer is A. That fifty percent is a statistic.
Step-by-step explanation:
Statistics is the science that studies the collection of objective data from reality and its subsequent analysis for the extraction of specific information on the group from which the data were obtained. Thus, statistics obtains different samples (such as opinions, personal characteristics, etc.) of a certain group, and compares their results with the purpose of establishing objective parameters applicable to the entire society.
In this way, the fact that in a survey 50% of the respondents answer in a specific way constitutes a specific statistic regarding that sample, which can in turn be transferred to society as a whole.

Answer:
$20.30
Step-by-step explanation:
The usual price of the gift is $29.00
Marie will get 30% DISCOUNT on this price if she uses her coupon. So, the final price would be 30% less than $29.00
First, we need to find 30% of $29.00. Then we need to subtract that from original price (29).
Convert percentage to decimal first:
30% = 30/100 = 0.3
Now multiply this with 29 to get:
0.3 * 29 = $8.70
We subtract this from original price to get DISCOUNTED PRICE:
$29.00 - $8.70 = $20.30
