hola cómo estás yo muy bien y tu qué tal
Answer:
1+1+2
Step-by-step explanation:
I'm the first one to answer to mark me Brainless!
since all sides are equal, which means all angles must also be equal to one another
all angles =60°
solving 7x-3=60
7x=63
x=9
similarly 11 y+5=60
11y=55
y=5
First answer is 27
Multiply -3 with -1
Then multiply it to the 3rd power.
2nd answer is 1 / 1296
First add the expoinents
-12 +8 = -4
Then you would need to do the equation
6^-4 x 6^0
And this would equal 1/1296
