(x + 3) ( x + 1 )
because 3 x 1 = 3 and 3 + 1 = 4 , which gives you 4x.
Answer: 48
Step-by-step explanation: multiply
Answer:
B. is dependent
Step-by-step explanation:
The denominator determinant will be zero when the coefficients of the variables are dependent. One of the numerator coefficients will be zero when the coefficients involved are dependent. Hence using Cramer's Rule will result in the ratio 0/0 when the system is dependent.
___
The ratio will be 1/0 if the system is inconsistent (has no solution).
What you have to do is multiply 0.42 by 8.3 million, then add that number to 8.3 million and you will have the total number of college students.
You have to set it up as a ratio 8/5 = y/10, then you have to cross mutliply and divide. So 8×10=80 and 80/5= 16 so y=16.
