Answer: The answer is A
Step-by-step explanation: Add the coefficient of x to the both sides.
X²+4x=12
X²+4x+4=12+4
X²+4x+4=16
X²+2x+2x+4=16
X(x+2)+2(x+2)=16
(X+2)(x+2)=16
(X+2)²=16
Answer: Insert a 6. The number divisible by 12 is 14<em><u>6</u></em>4
Step-by-step explanation: Start by dividing 12 into the first two digits.
I am using old-fashioned long division.
<u>1 2</u>
12 ) 14 <u><em>6</em></u>
-<u>12</u>
26. this is the remainder, The next digit has to be a number that when divided by 12 will leave a remainder, that when paired with 4, will be evenly divisible by 12.
6 is that number . When you "bring down" the 6, you will be dividing 26÷12. a 2 goes into the quotient, and in the next step 24 is subtracted from 26; the remainder is 2.
Bring down the 4 and divide 12 into 24. The result is 2 as the quotient. 2 ×12 =24 . 24- 24 is 0
1464 ÷ 12 = 122
Answer:
1=28 students 2=14students 3=40%
Step-by-step explanation:
<u>1.</u> 70 students = 100%
7 students = 10%
28 students = 40%
28 students are sixth graders!
<u>2.</u>70 students = 100%
7 students = 10%
14 students = 20%
14 students are seventh graders!
<u>3</u>.Percentage of band that is eighth graders: 40+20=60% 100%-60%=40%
40% are eighth graders!
