Answer:

36.

explanation:

We have been given an equation and we are asked to find the number that should be added to both sides of the equation to complete the square. To complete the square we divide the constant with x term by two and add the square of that number to both sides of equation to complete the square.We can see that constant of x term is 12, so let us divide 12 by 2. Therefore, we should add 36 to both sides of our equation to complete the square.

You can add a lot of numbers (or so I think). One number I think you can add is 31.

I really need help with this, my teacher doesn't really teach and I'm stumped again.

Answer:

JMK = 54

JKH = 126

HLK = 90

HJL = 27

LHK = 63

JLK = 27

Step-by-step explanation:

Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54

So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.

The skating rink rented 218 pairs of skates during the month of April and 3 times that many in May. How many pairs of skates did

Marrrta [24]

Answer: Total number of pairs =872

Step-by-step explanation:

Since we have given that

Number of pairs of skates during the month of April =218

Number of pairs of skates during the month of May =3 × 218=654

As we know that total means altogether in which we perform the additive operation.

Total pairs of skates the skating rent during April and May = 218+654=872

∴ Total number of pairs =872
