Answer:
The zeros are 6,-5,9
Step-by-step explanation:
The factored form of the polynomial is given as:
To find the zeros of this function, we set f(x)=0 and solve for x.
This implies that:
We solve for x to get:
The zeros are 6,-5,9
The length of the unknown leg of the triangle is 15 m.
<u>Step-by-step explanation:</u>
Length of one leg = 20 m
Length of the hypotenuse= 25m
As it is a right angled triangle we can use pythogoras theorem.
Let the unknown length be y
(20) (20) + y(y) = (25) (25)
400 + y(y) = 625
y(y) = 225
y = √225
y = 15
The length of the unknown leg is 15 m.
Answer:
-1 i believe because that is the only x intercept. i apologize if this is wrong
Step-by-step explanation:
Answer:
3/2(x+y)
Step-by-step explanation:
The cost of 2 DVD is x+y
Divide by 2 to get the cost of one DVD
(x+y) /2
Multiply by 3 to get the cost of 3
3/2(x+y)
4 and 8/10 but simplified it's 4 and 2/5
