Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.
-- Remember this only works on perfect square polynomials.
Answer:
$825
Step-by-step explanation:
Given that :
Weekly earning = $600 plus 3% of sales over $6500
If weekly sales = $14000
How much will Robin earn
Robin's earning will be:
Flat weekly pay + 3% of amount over 6500
$600 + 3%(weekly sales - 6500)
$600 + 0.03(14000 - 6500)
$600 + 0.03(7500)
$600 + $225
= $825
Answer: Day 14
Step-by-step explanation: 2^14 = 16384 cents, which equals $163.84
4a^2c^2(a^2-b^2+c^2)^2
First, solve the exponent around the quantity. Being that it's a power of a power, you would multiply all the exponents inside the parentheses by two. So, after that, it would be:
4a^2c^2(a^4-b^4+c^4)
Then, you would multiply what's outside the parentheses with every term within the parentheses:
(4a^6c^2)-(4a^2c^2b^4)+(4a^2c^6)
Now, you think you can take it from here, or do you need me to keep going?
Answer:
25
Step-by-step explanation:
5=20% of x
0.20x=5
divide both sides by 0.20
x=25
