If Mallory makes $42.50 per hour and she works 20 hours a week, we multiple those two and we get:
42.5 * 20 = 850
So she earns $850 per week.
Mallory saves half of that amount she would have $425 per week.
In 4 weeks she would have:
425 * 4 = 1700
Mallory will save $1,700 in four weeks.
Given:
A right angled triangle.
To find:
The value of x.
Solution:
We have,
Base = x
Hypotenuse = 
In a right angle triangle,
For the given triangle,
Multiply both sides by .
Therefore, the required value of x is 
.
f(x) = -3x2(x - 3)(x + 4)3(x2 + 5)
If (x - a) if a factor of polynomial P(x), then a is a zero of P(x).
x = 0
x = 3
x = -4, three times
x = ±√5
