Answer:
the number before the first variable (first term)
Step-by-step explanation:
this appears to be an incomplete question. The numerical coefficient of a term is the number before the variable.
the constant is the number without a variable.
30/5 is 6, so c/3 is 6, and c is 6x3, so c is 18.
Answer:
12
Step-by-step explanation:
just find the HCF, which will be
2² × 3 = 12

Multiply the square root of 3 by the square root of 2 and itself.
The 3 cancels itself out and then you get A
To find the residual I would subtract the predicted value from the measured value so for x-value 1 the residual would be 2-2.6 = -0.6
