Given expression is 2 y √ ( 2 (x + y ) .
Here x = 1 and y = 4 .
We have 2 ( x + y ) in square root in the given expression .
To find the answer of the given expression , we need to plug the given values
of x and y .
We plug " 1 " in place of x and " 4 " in place of y .
Then we need to simplify the given expression .
Please see the attachment .
On simplifying we get 8 multiply square root 10 .
Value of square root 10 is 3.1623 .
Thus the value of the expression is 8 * √10 = 8 * 3.1623
= 25.2982 .
Answer:
4. z = -1
5. x = 3.5 or 7/2
Step-by-step explanation:
4.
-4z + 8 = 7z +14 + 5
-4z + 8 = 7z + 19
8 = 11z + 19
-11 = 11z
-1 = z
5.
6-x/5 = 6-3x+6/3
6-x/5 = 12-3x/3
18 - 3x = 60-15x
-3x = 42 - 15x
12x = 42
x = 3.5 or 7/2
