Five times a variable equals the variable to the third power
Answer:
C
Step-by-step explanation:
- example : (5+2)² = 5² + 2.5.2 + 2² = 49
9x² + 6x + 1
9x² = (3x)²
1 = 1²
6x = 2.3x.1
So => 9x² + 6x + 1 => <em>(3x + 1)² </em>
Hope this helps ^-^
In math, "of" usually means "times".
2/3 x 3/4 = 6/12 = <em>1/2 pound</em>.
Answer:
9 years.
Step-by-step explanation:
For 50 raccoons the equation is
0.4x^2+2x+2 = 50
0.4x^2+2x - 48 = 0
x = [-2 +/- sqrt(2^2- 4* 0.4*(-48)] / (2*0.4)
= (-2 +/- sqrt 9) / 0.8
= 8.74 , - 13.75 (ignore the negative).
So it's 9 years.
