Answer:
the correct answer is -5 since y=7
Answer:
discriminant =0
1 real root
Step-by-step explanation:
The discriminant is b^2 -4ac
when the equation is written in the form ax^2 +bx+c
f(x) = 3x^2 +24x+48
a = 3 b = 24 and c =48
discriminant = 24^2 - 4(3)*(48)
=576-576
=0
If the discriminant >0 we have 2 real roots
if discriminant = 0 we have 1 real root
if discriminant <0 we have 2 complex roots
The length would be 50 ft and the width would be 40 ft.
Answer: x = 20
Step-by-step explanation:
We can use the pythagorean theorem:
x^2 + 15^2 = 25^2
x^2 + 225 = 625
We can subtract 225 from both sides:
x^2 = 400
We can take the square root of both sides:
x = 20.
