Given: <span>10g^2+33g=9-2g^2
Group the q^2 terms first, then the q terms, and finally the constants:
12g^2 + 33q - 9 = 0. Make sure you agree with this, or otherwise fix it.
Tools for solving quadratic equations include the following and more:

completing the square
I've graphed this simplified quadratic on my TI-83 calculator and see that -3 seems to be a root. Let's check it!
________________
-3 / 12 33 -9
-36 9
---------------------
12 -3 0 Since the remainder is zero, -3 is a root and (x+3) is a factor. The other factors are 3 and (4x -1)
Then 3(4g-1)(g+3) = 0, with the result that g = 1/4 and g = -3.
Please check these roots by subst. into the original equation.</span>
Step-by-step explanation:
the perimeter =
4+4+6+4.5+2+4+4+2 =
30.5 cm
the area of:
• the bigger rectangle = 6×4 = 24 cm²
• the smaller triangle = 4×2 = 8cm²
• the triangle = ½×2×4 = 4cm²
the total area = 24+8+4 = 36cm²
Answer:
It's C or the third option.

Answer: 13
Step-by-step explanation:
First, we have to arrange the numbers in either ascending or descending order.
12,11,13,12,15,16, and 14 hours will then be: 11, 12, 12, 13, 14, 15 and 16.
The median will be gotten using the formula: = (n + 1) / 2
Since there are 7 numbers this will be:
= (n + 1) / 2
= (7 + 1) / 2
= 8/2
= 4th number
Since 13 is the 4th number, it's the median
Answer:
C. & D
Step-by-step explanation:
This would be the answer since countering the others it's 90 degrees. While the others are able to add up to 180 degrees. :)
