the answer is a
A.
A=0 b=0 c=0
2a. (a, b and c are all equal.)
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
the answer is a
Oh, isn't that a lovely question! When you add b plus b plus b plus b, you are actually adding 4 "b's" together. So, it's like having 4 beautiful little b's all snuggled up together, creating 4b. Just imagine those b's painting a happy little equation on the canvas of mathematics.
Yes because if 1+0=1 than 0 plus b equals b
a=24 b=16 c=18
Because there is no way to define the divisors, the equations cannot be evaluated.
a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)
A.
a+b=a+b
a = 20 b = 60 c = 100
A=0 b=0 c=0
12
B=61
