The answer is D. To help find the answer, you can remember an easy rule. The rule is if you're subtracting a positive number from a negative number, it will always be negative thus eliminating any answers that are positive.
7.13 because you would need to add the decimals together
Answer:
Step-by-step explanation:
x = 8
-5x^3 + 2x^2 + 1
a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.
so in ur problem....there are 2 coefficients..-5 and 2.
** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.
** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.
okay...I am gonna shut up now :)
Answer:
0.8 < x < 16.8
Step-by-step explanation:
The third side of the triangle is always less than the other two sides combined. I think of it like if it was greater than the other two sides added, there would be no triangle- it'd be a line.
The other rule is that it has to be greater than the difference between the two lines.
I hope this helped!
