Answer:
x-3
Step-by-step explanation:
(x+5)(x-1)(height)=x3+x2-17x+15
x2+5x-1x-5(h)=x2+4x-5
so what times x2+4x-5 will equal the volume
look at the constant -5 and think what will multiply with that to get 15 so -3 right so then check the rest of it by doing (x2+4x-5)(x-3) =x3−3x2+4x2−12x−5x+15
=x3+x2−17x+15 so the answer is x-3
Hope this helps! :)
Answer:
(3x + 1) (2x + 1)
Step-by-step explanation:
ax² + bx + c can be factored using the AC method:
1. Multiply a and c.
2. Find factors of ac that add up to b.
3. Divide each factor by a; reduce the fractions.
4. The denominator is the coefficient, the numerator is the constant.
6x² + 5x + 1
1. ac = 6 × 1 = 6
2. Factors of 6 that add up to 5: 2 and 3.
3. 2/6 = 1/3, and 3/6 = 1/2
4. The factors are 3x+1 and 2x+1.
6x² + 5x + 1 = (3x + 1) (2x + 1)
Answer:
x=20
Step-by-step explanation:
2x+34= -26+5x
-2x -2x
34=-26+3x
+26 +26
60=3x
(divide by 3)
20=x
Given that she slides at a rate of 8m/s and that she was 5 m of the ground after 3 seconds, the number of seconds it takes her to reach the ground from the current position is given by:
![t=\frac{d}{s}=\frac{5}{8}seconds](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bs%7D%3D%5Cfrac%7B5%7D%7B8%7Dseconds)
Therefore, the number of seconds it takes her to slide to the ground from the top is given by:
