it has no root
first make it common quadratic form
y = 5x² - 3x + 8
we take
a = 5
b = -3
c = 8
the to prove it doesn't have root. we using discriminant
D = b² - 4ac
D = (-3)² - 4*5*8
D = 9 - 160
D = - 151
D > 0 means the equation has 2 roots
D = 0 means the equation has 1 root
D < 0 do not have root because it doesn't have intercept on x-axis
So, let’s find out the numbers needed to form the ratio. The length of the swimming pool is 50 ft long. We need to find the perimeter. 2(50+35)
2*85
170.
So, the perimeter is 170 ft. Now we need to form the ratio. Length is first, then the perimeter.
50:170 is your ratio, but we can simplify it to 5:17. Hope this helped!
Answer:
Step-by-step explanation:
4x^2(x^2 - 5x + 6)
4x^2(x - 3)(x - 2)
Answer:
1/6
Step-by-step explanation:
There are six sides on a die and only one of them has a 4
P( 4) = number of sides with a 4/ total number of sides
= 1/6
Answer:
A
Step-by-step explanation:
Add 3x^2 and 5x^2 now it = 8x^2
Add -8x and -4x = -12x
look at your answer choices the only one that has 8x^2-12x is A
