Step-by-step explanation:

The coefficient of the x term in your X^2+12x=11 is 12.

Take half of that, obtaining 6.

Square this result, obtaining 36.

Add this number to both sides, obtaining x^2 + 12x + 36 = 11 + 36

Find two numbers, if Their sum is −7 and their difference is 14

Schach [20]

let those numbers be x and y

According to your question

x + y = -7

x - y =14

adding both equations

2x = 7

or x = 7/2

substitute value of x in either equation

y = -21/2

So,

x= 7/2

y=-21/2

Hope this helps!

Find the least common denominator of 3/8 and 11/2

Elden [556K]

Answer:

Step-by-step explanation:

Note that 2 divides into 8 evenly, yielding the quotient 4. 8 is the LCD. To combine 3/8 and 11/2, we would rewrite 11/2 as

4·11

------ = 44/8

4·2

and then combine 44/8 with 3/8. The sum would be 47/8.

In summary, the LCD of 3/8 and 11/2 is 8; 3/8 stays as is and 11/2 is rewritten by mult. numerator and denominator by 4 each.
