Step-by-step explanation:
At first we use "BODMAS" rule.
Given,
(3.5×10^13)-(1.4×10^12)/3×10^9
So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.
Use "Number" instead of "general" in the excel sheet. You can use calculator too.
Answer: 2a - 7
<u>Step-by-step explanation:</u>
Ana: a
Mrs Vargas: 4a - 4
Leo: 2a + 3
Mrs Vargas - Leo
= (4a - 4) - (2a + 3)
= 4a - 4 -2a - 3
= 2a - 7
Answer:
54 minutes
Step-by-step explanation:
The sum of fractions is ...
2/5 + 3/20 + 1/3 = 11/20 +1/3 = (3·11 + 20·1)/(20·3) = 53/60
Then the 42 minutes devoted to English represents 1 - 53/60 = 7/60 of her study time.
Kaya's social studies time is 3/20 = 9/60 of her total, so the ratio of SS to Eng is ...
SS : Eng = (9/60) : (7/60) = 9 : 7
When we multiply the numbers in this ratio by 6, we find ...
SS : Eng = 54 : 42
Kaya spent 54 minutes studying social studies.

A polynomial is defined as a collection of variables and constant terms combined by various mathematical operations. The exponents of the variables in a polynomials must be non-negative integers.
If you observe the given options, one of the option (option B) contains a negative exponent. Hence the expression in option B is not a polynomial.
