The answer is (14) just add them all up
Answer:
9
Step-by-step explanation:
because 7 x 9 equals 63
Answer:
Explanation:
Please, see attached the chart corresponding to this question.
The<em> chart</em> is a pie chart that shows the percentage composition of the <em>expenses </em>and uses color to identify each item.
The items corresponding to<em> taxes</em> are:
- <em>Federal tax: 29%</em>
- <em>State tax: 6%</em>
All the other expenses are not taxes.
Add the two items that are taxes: 29% + 6% = 35%.
Hence, the expenses that are not taxes can be calculated by difference:
The answer is: x = 7 - √53 or x = 7 + √53
The general quadratic equation is: ax² + bx + c =
0.
But, by completing the square we turn it into: a(x + d)² + e = 0, where:<span>
d = b/2a
e = c - b²/4a
Our quadratic equation is x² - 14x -4 = 0, which is
after rearrangement:
So, a = 1, b = -14, c = -4
Let's first calculate d and e:
d = b/2a = -14/2*1 = -14/2 = -7
e = c - b²/4a = -4 - (-14)</span>²/4*1 = -4 - 196/4 = -4 - 49 = -53<span>
By completing the square we have:
a(x + d)² + e = 0
1(x + (-7))</span>² + (-53) = 0
(x - 7)² - 53 = 0
(x - 7)² = 53
x - 7 = +/-√53
x = 7 +/- √53
Therefore, the solutions are:
x = 7 - √53
or
x = 7 + √53
