Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
I think that the answer is A, because in the range, none of the numbers should be the same, and the numbers are all different in choice A
Answer:
I think system 4 has no solution
Step-by-step explanation:
I'm sorry if you get it wrong
-6*3 =-18
11*4=44
-18/44. Reduce. Divide top and bottom by 2
-9/22
