Answer:
-2
Step-by-step explanation:
-59 - 2 + 29 - 8 = -61 + 29 - 8
Here -59 & -2 have same sign, so add both
= -61 - 8 + 29
= - 69 + 29
-69 & 29 have different sign. so subtract and the answer will have the sign of the bigger number
= - 40
By geometric mean theorem,
In a triangle ABC,
y² = 60
y = √60
y = 7.75
Similarly,
x² = 40
x = √40
x = 6.32
$20.40
I LOOKED IT UP
L'(-7, -7), M'(-9, 9), and N'(5, 5)
Assuming you mean 90° counterclockwise, you would use the formula: A(x,y) becomes A'(-y,x)
so L'(-7, -7), M'(-9, 9), and N'(5, 5)
