Expanding the left side of the equation, it is found that since <u>both sides are equal</u>, yes, it is an identity.

An equality represents an identity if <u>both sides are equal</u>.

In this problem:

(a - b)^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

Expanding the left side:

(a - b)^2(a - b)^2 = a^4 - 4a^3b + 6a^2b^2 + 4ab^3 + b^4

(a^2 - 2ab + b^2)(a^2 - 2ab + b^2) = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

a^4 - 4a^3b + + 6a^2b^2 - 4ab^3 + b^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4

Since <u>both sides are equal</u>, yes, it is an identity.

Shkiper50 [21]

Answer:

$215.16

Step-by-step explanation:

Thursday - 7.14

Friday - 5.14

Add all the hours together: 4.14+3.14+7.14+5.14 = 19.56. Now times the hour by his rate of $11.

19.56(11) = $215.16

Which sum is close to 1 0.4+1/2 ,7/8+1/4,4/5+2/3 explain
serg [7]
Presuming the question is "Which sum is closest to 1". 
First, you need to either convert all the fractions to decimals or all the decimals to fractions, then add each pair. 
0.4 + 1/2 = 0.9
7/8 + 1/4 = 1.125
4/5 + 2/3 = 1.466666...
The first one is different from 1 by 0.1. The second is different by 0.125. The third is different by 0.46666.... Therefore, the closest sum is the first, or 0.4 + 1/2

0.4 + 1/2
