Answer:

7x + 4y + 8

Step-by-step explanation:

Please be more explicit regarding your goal.  "What is ... " could be interpreted in several ways.  I will assume you meant, "What is the simplest form of 3x + 4(x + 2) + 4y?"  Finally, please use the regular character, " x, " when you mean a variable and use the character " × " for multiplication.

What is the simplest form of 3x + 4(x + 2) + 4y?  Do the indicated multiplication.  We get:  3x + 4x + 8 + 4y, which in turn is 7x + 4y + 8.

320 students. Because you have to divide 384 by 6 which will give you 64 which is the number for the students that chose art and then subtract that from the total students which are 384 and you'll get 320 as your answer for the student that didn't pick art.

OleMash [197]
Answer:  No.  To the contrary,  "12,000,000" is the "standard form" of 
                "1.2 times 10 to the POSITIVE 7 power.

That is;  "12,000,000 = 1.2 * 10⁷ " .

Half of allen's test score plus 8 equals 50. what did Allen score on his test?
Dmitry [639]
Let x= Allen's score

1/2x +8=50
multiply by 2 to eliminate the fraction
x+16=100
subtract 16 from both sides
x= 84 is Allen's test score

hope this helps
