Answer:
18
Step-by-step explanation:
2x9=18
For this problem, you would use the Pythagorean Theorem (a^2 + b^2 = c^2)
A and B are the length and width of the triangle. The triangle is created by the diagonal line splitting the computer screen. C is the hypotenuse, which is the diagonal line, and will always be the longest side of the triangle.
When we plug in the numbers into the formula, we would get this:
13^2 + b^2 = 15^2
B is the unknown variable in which we are trying to find.
First, you square 13 and 15:
169 + b^2 = 225
Then, subtract 169 from both sides:
b^2 = 56
Finally, find the square root of both sides:
b = 7.483314774
Simplify to the nearest tenth, and the answer is 7.5<span />
Answer:
1. Yes the parentheses are necessary. To find a fourth of her regular hours you must find the total amount she works during her regular hours.
2. 6
Step-by-step explanation:
(For the second question)
4+8= 12
12 × ½ = 12 ÷ 2
12÷2 = 6
<h3><em>
My friends the answer is 3.</em></h3>
<em> 24.95 + 18.96 + 17.55 + 23.14 + 12.00 + 96.60</em>
<em> 4 divided by 12 is 3</em>
<em></em>

<em></em>
(2+5x)-2=18
2+5x-2=18
5x=18
x=18/5= 3.6
