Answer:
Polynomial equation is x² - 16
Her pay if x = 12 is $128
Step-by-step explanation:
This week, Kyara worked x + 4 hours
She is paid x - 4 dollars per hour
She earned (x + 4)(x - 4) = x² - 16 dollars this week
Her pay if x - 12 is;
12² - 16 = $128

<h3>What is law of exponents ?</h3>
The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 34 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. A whole number, fraction, negative number, or decimal are all acceptable.
<h3>How are powers of powers multiplied?</h3>
Exponents with distinct bases and the same powers can be multiplied by multiplying the bases and writing the power outside of the brackets.

<h3>Answers:</h3>
1% of 300 is <u> 3 </u>
So 64% of 300 is <u> 192 </u>
========================================
Further explanation:
To take 1% of 300, we just chop off the extra zeros. So that's how I got 3.
To go from 1% to 64%, that's a jump of "times 64". Meaning you multiply that '3' by 64 to get 64*3 = 192.
Notice that 192/300 = 0.64 = 64% to confirm the answer.
Answer:
x= 1.069Y
Step-by-step explanation:
kilometers = y
miles = x
y>x
5x = 8.045y
therefore,
8.045 divided by 5 to get value of X
hence,
X = <u>1.069Y</u>
