Add ten to both sides:
K = 13
To check my work you can plug 13 in for k:
13-10=3
Hope this helps (:
Step-by-step explanation:
2 < x < 4 and 3 < y < 7
We have (2 + 3) < (x + y) < (4 + 7),
Therefore 5 < x + y < 11.
The largest integer value for
x + y is 10.
Answer:
1/5x^12 * y^8.
Step-by-step explanation:
((5x^8*y^7/25)x^4)(y)
=1/5x^12 * y^8.
Answer:

Step-by-step explanation:
4+1.5=5.5
8-5.5=1.5
1.5/.75=2
X² +18x = 0
To complete the square we are going to use formula a² +2ab +b² = (a+b)²
x² +2*9*x = 0
x² +2*9x+9² = 9²
(x+9)² = 9²
√(x+9)² = +/-√9²
x+9 = 9, or x+9 = -9
x=0, or x= - 18
The equation could be solved different way
x² +18x = 0
x(x+18) = 0
x=0 or x+18=0
x=0 or x=-18
