“x” represents an undefined term
ex: 9x-2
Please give brainliest :)
Step-by-step explanation:
5x^2+2x=1
5x^2+2x-1=0
x=-b+/-√b^2-4ac÷2a
x=-2+/-√-2^2-(4×5×-1)÷2×5
x=-2+/+√4--20÷10
x=-2+/-√24÷10
x=-2+√24÷10 or -2-√24÷10
x=-2+4.9÷10 or -2-4.9÷10
x=2.9÷10 or -6.9÷10
x=0.29 or -0.69
Answer:
The Answer is D
Step-by-step explanation:
All you do is add both equations 3^x+10x+2x-4
then you add the like varibles which is 10x+2x=12x
So, the answer is 3^x+12x-4
