You set up the problem correctly, just keep going.
Expand out your expression:
2x(3x-9) + 4x(x+13)
= 6x^2 -18x + 4x^2 + 52x
= 10x^2 +34x
Remember that the above expression is the area, so it is equal to 24.
10x^2 + 34x = 24
10x^2 + 34x - 24 = 0 (divide by 2)
5x^2 + 17x - 12 = 0
Done.
Answer:
The answer is B. No solution
Step-by-step explanation:
16x^2 is not equal to 100, so the equation is false, and there is no solution for x.
Answer:
Mean: 20
Median: 20
Step-by-step explanation:
Mean: 10, 15, 18 22, 25, 30 =120/6=20
Median: 10, 15, 18 22, 25, 30= 18+22=40/2=20
X = 14 inches.
you can solve this by using proportions.
8/20 = x/35
280 = 20x
/20 /20
14 = x
The degree of the derivative is 9, so t<span>he maximum possible number of turning points is 9.</span>
