Answer:
15
Step-by-step explanation:
2/3x=10
You divide it and then you get your answer.
Hello there!
I can assume you mean "Pi".
Pi is an irrational number that has an infinity decimal, also known as a terminating decimal, which means to repeat infinitely.
The summarized form of Pi is 3.14, but since you have multiple units, I can assume you want the extended form.
Here it is:
3.14159265359
I hope this helps!
( 2x − 27 ) ( −x + 15 )
= ( 2x + −27 ) ( −x + 15 )
= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )
= −2x^2 + 30x + 27x − 405
= −2x^2 + 57x − 405
First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1
</span>
