Answer: X = 10.20240940...
Step-by-step explanation:
x(2x + 9) = 2x^2 + 9x
2x^2 + 9x = 300
- 300 ON BOTH SIDES
2x^2 + 9x - 300 = 0
SOLVE USING THE QUADRATIC FORMULA
x = -b +/- all root (b)^2 - 4(a)(c) All over 2(a)
When all the values are plugged in:
When using "+" in the equation you should get:
x = 10.20240940…
When using "-" in the equation you should get:
x = −14.70240940…
Now.. you CANNOT have a negative length, so you cross of the negative value leaving you one value for x which is 10.20240940...
YOUR ANSWER IS: x = 10.20240940...
Answer:3(3+5)
Step-by-step explanation:9 +15
=3(3+5)
You have to find the gcf of 9 and 15 which is 3 .So then next you know that you have to use 3 so u have to think what 3 times ? gives you 9 which is 3 and you have to think what 3 times ?gives you 15 which is 5.And now u write 3 then a parthness and a 3 and the addition sign which is from the question and lastly 5 which gives you 3 (3 +5)
Hope this help,please give Brainliest if it does.thanks! :)
The distance between the two numbers is 23
No it is 15\ five so the correct answers is number 2 if it was five divided by fifteen it would be 0.3 which is wrong so jus to clarify the answer is the second one.
-16 and -1 multiply to be 16, but add to be -17
