Answer:

y\in(-\infty ,-3)\cup(7,\infty )

Step-by-step explanation:

We have been given the compound inequality

y -2 < -5 or y -2 > 5

Since 2 is in subtraction with y hence in order to eliminate it we can do the reverse operation of subtraction which is addition.

Hence, add 2 to both sides

y -2+2 < -5+2 or y -2+2 > 5+2

y < -3 or y > 7

In interval notation, we have

y\in(-\infty ,-3)\cup(7,\infty )

The graph has been shown in the attached file.

A carpenter wants to expand a square room. The new room will have one side 4 feet longer and the adjacent side 6 feet longer tha
gogolik [260]

Answer:

  Dimensions of original room = 12 x 12 feet.

Explanation:

 Let the size of old square room be a x a.

 New dimension = ( a+4 ) x ( a + 6 )

   We have area of the new room will be 144 square feet greater than the area of the original room.

  So,     ( a+4 ) x ( a + 6 ) = a x a + 144

              a²+10a+24= a²+144

              10a = 120

                  a = 12 feet.

 Dimensions of original room = 12 x 12 feet.
