Answer:
d=15
Step-by-step explanation:
So in this question we are using the Pythagorean Theorem. a^2 + b^2 = c^2
The side opposite to the right angle is the hypotenuse.
So to solve the equation put in the values for a and b.
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
Now take the square root of 225
= 15
so d = 15

Answer:
-361
Step-by-step explanation:
Your calculator can tell you the result. It is -361.
Start with the inner parentheses and work outward. Do multiplication and division in the order shown, left to right, before addition or subtraction.
-3[2/6+8{-9/3(8-5*3)-6}]
= -3[2/6+8{-9/3(8-15)-6}]
= -3[2/6+8{-9/3(-7)-6}]
= -3[2/6+8{-3(-7)-6}]
= -3[2/6+8{21-6}]
= -3[2/6+8{15}]
= -3[1/3+8{15}]
= -3[1/3+120]
= -3[361/3]
= -361
