8 x a = 8 x (-2) = -16
-16 + b = -16 + 3 = -13
-13 is the answer
Step-by-step explanation:
Find the gradient of AB
-2.5
Find the gradient of perpendicular
0.4
Make the equation
y= 0.4x + c
Apply point A
3= 0.4*2+c
3-0.8= c
c= 2.2
y= 0.8x + 2.2
Square root 270 a^2 b^2
3sq root 30 a^2b^
Answer:
13
Step-by-step explanation:
56 divided by 7 equals 8
210 divided by 10 equals 21
And if you subtract 21-8 you get 13 #helping the 3rd graders
