Answer:
x=9
Step-by-step explanation:
x+18=2x+9
-x -x
18=x+9
-9 -9
9=x
x=9
Answer:
I think it’s X=1
Step-by-step explanation:
2/3x+1/6=-1/2x
1/6=-1/2x-(-2/3x)
1/6=1/6x
X=1
4x+3(-3x-1)=2. This is gonna lead to x=-1 and y=2
Answer:
( a+b) (a-b)
x^2 - 50
Step-by-step explanation:
The formula for difference of squares is
a^2 - b^2 = ( a+b) (a-b)
121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares
x^2 - 16y^2 = (x)^2 - (4y)^2 so this is the difference of squares
9x^2 -64 = (3x)^2-8^2 so this is the difference of squares
x^2 - 50 = (x)^2 - 2*(5)^2 this is not the difference of squares
Answer:
66
Step-by-step explanation:
Find other side:
116 + x = 180
-116 -116
------------------
x = 64
Find missing triangle angle:
50 + 64 + x = 180
114 + x = 180
-114 -114
-------------------
x = 66
Hope this helped.
