Factor the polynomial using the rational roots theorem (x+1) (x−5) (x−2)
How<span> you would factor this is,
</span>The two terms of the binomial equation 25x<span>^2 + -9 = 0 are perfect square. When factoring the difference of two perfect squares: x^2 – a^2 = (x+a)(x-a) . STEP 2: Set up and solve the equation. (5x) (5x) + (5x) (-3) + (3) (5x) + (3) (-3) = 0 With the Distributive Prop

Answer:
12 pistachios
Step-by-step explanation:
We need to find the unit rate. So we divide 5 from 15.
15/5=3
So we know that 1 bowl has 3 pistachios(which I think needs more).
Now we need to find how many pistachios are in 4 bowls. Which means we multiply 4 and 3.
4x3=12
So there are 12 pistachios in 4 bowls.

Answer: the speed of the current is 9 mph.
Step-by-step explanation:
Let x represent the speed of the current.
A boat can travel 21 mph in still water. If it travels 270 miles with the current. It means that the total speed with which the boat travelled with the current is (21 + x) mph.
Time = distance/speed
Time spent by the boat in travelling 270 miles is
270/(21 + x)
In the same length of time, it travels 108 miles against the current. It means that the total speed with which the boat travelled against the current is (21 - x) mph.
Time = distance/speed
Time spent by the boat in travelling 108 miles is
108/(21 - x)
Since the time is the same, then
270/(21 + x) = 108/(21 - x)
270(21 - x) = 108(21 + x)
5670 - 270x = 2268 - 108x
108x + 270x = 5670 - 2268
378x = 3402
x = 3402/378
x = 9
