First lets distribute the 5x
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i
Answer:
Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
solve for x
Find the angle measurements
If I’m correct 500-35=465 then 465 divided by 2 and u got 232.5 and they said. At least 2 for each so I would go with 232 aka b
The price of the Xbox One after tax is $265
<h3><u>
Solution:</u></h3>
The price of a Xbox one is $250
The tax on Xbox one is 6%
Now, the tax of 6% on 250 is calculated as follows:-
So, the tax on Xbox one is $15
The total price of box including tax can be calculated by adding price of box and tax on box
<em>Total price of Xbox after tax = actual price of the Xbox One + Tax on the Xbox One
</em>
= $250 + $15
= $265
Hence, the price of the Xbox One after tax is $265
Answer:
58.5
Step-by-step explanation:
This expression should be simplified using order of operations. According to order of operations or PEMDAS, complete any numbers in parenthesis then any exponents, multiplication, division, additions and subtraction moving left to right through each operation.
Begin with Parenthesis.
(7+3-4*9) - Multiply first
(7+3-36) - Then add/subtract left to right
10 - 36 = -26
Replace -26 where the parenthesis were in the original expression.
9/4 (-26)
234/4
58.5
