The product of two consecutive even integers is 32 less than the square of the greater integer. Find the smaller integer.
Lilit [14]

Answer:

The smallest even integer is 14

Step-by-step explanation:

Given as :

The product of two consecutive even integers is 32 less than the square of the greater integer.

Let the smallest even integer = 2 x            ...........1

And The greatest even integer = 2 x + 2            ..........2

<u>Now, According to question</u>

smallest even integer × greatest even integer = (greatest even integer)² - 32

Or, (2 x + 2) × 2 x =  (2 x + 2)² - 32

Or, 4 x² + 4 x =  4 x² + 8 x + 4 - 32

Or,  (4 x² + 8 x) - (4 x² + 4 x) = 32 - 4

Or, (4 x²- 4 x²) + (8 x - 4 x) = 28

Or, 0 + 4 x = 28

∴ x = \dfrac{28}{4}

I.e x = 7

Now, pout the value of x in 1

So, The smallest even integer = 2 x = 2 × 7 = 14

Hence, The smallest even integer is 14  Answer

To answer this question you will need to calculate the mean for each of the Shifts and then compare those means to the mean of all the data given.  I have attached a picture of the means for each shift and the population mean (all the data).

Shift 1 is the closest to the population mean.  It is 37.4, and the population mean is 35.9.

If an item costs $45 and we must pay 6% sales tax, how much will we pay for the item?
Gennadij [26K]

$47.70

$45 with 6% sales tax

6%=.06

To find total amount multiply by 1.06 or multiply by .06 and that is tax amount and then add it to the $45

$45*.06=2.70 amount of tax

$45*1.06=47.70 total amount paid

Any questions feel free to ask. Have a great day!
