Answer: 112.32
Step-by-step explanation:
Answer:
First blanks: 36 and 36
Second blanks: -7 or 7
Step-by-step explanation:
Simplify (x+6)^2 and you get x^2+12x+36. 36 is what’s missing in that blank, and it needs to be added to both sides. Next, the second set of blanks is what you get when you take the square root of both sides of the equation. Sqrt((x+6)^2)=x+6. Sqrt(49)= -7 or 7. So you have to put 7 and -7 in the second set of blanks.
Y = 2
y/4 + 2/3 = y/3 + 1/2
2/4 = 1/2
2/3 = 2/3
2/4 + 2/3 = 2/3 + 1/2
The only irrational number there is C
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
