Answer:
-11.55
Step-by-step explanation:
(to get the numbers out of the brackets you have to multiply all the numbers in the brackets to the number that is there, and in this case its 1.5)
1.5x(-2.4)= -3.6
1.5×(-5.3)= -7.95
after that, you add them (because there is a plus sign, not a minus, multiplication sign or a division sign.)
-7.95+ -3.6= -11.55
answer= -11.55

Answer: Choice C) x^4 - 2</h3>
Explanation:
If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.
Answer:
Step-by-step explanation:
Step 1
