Ax+b=r
ax=r-b
x=(r-b)/a
Were there supposed to be constant values to the variables or...?
√a x √b =√axb so find 2 numbers that multiple to make the number (1 must be a square number)
√90 can be split into √9 x √10 and √9 is 3 so is 3√10 and the next questions are solved the same
√306 is 3√34
√73 is 3√8
√236 is 2√59
√3600 is 60
√5120 is 8√80
Angle A is 50 degrees
Angle B is 130 degrees
AB is is 20 feet
A. When you equalize two equations, geometrically you are trying to find the intersection point of them, i.e. find the common point of them. So the x coordinate of the intersection point is basically the solution.
B. You can simply plug in numbers from -3 to 3 and list the values by yourself.
C. Graphically, draw each equation, and find the x coordinate of the intersection point.
FYI, the solution is x = 1/3
