Answer:
22 is th area
Step-by-step explanation:
Y=kx+b
line is perpendicular y=1/3x+6⇒ k=-

=-3
so line y=-3x+a
this line that passes through (-9,12)⇔x=-9, y=12, so 12=-3(-9)+a
12=27+a
a=12-27
a=-15
y=-3x-15

Answer:
It would be 2
Step-by-step explanation:
Since they are looking for only 1 significant fig. you would round the number that would make this correct, for example:
You would look at 1.7 and ignore the others...
7 is greater than 5 so it'll affect the 1
And that how you get 2 : )
-10=-19 is the answer goodluck
Area = b * h
Area of orange = area of big square subtract by area of small square
Small square = b^2
Big square = a^2
(a^2 - b^2) = (a - b)( a + b)
Solution: (a - b) (a + b)
