ANSWER
3
EXPLANATION
The given polynomial is
![{a}^{2} + b - cd](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20b%20-%20cd)
The terms of the polynomial are:
First term:
![{a}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20)
Second term:
![b](https://tex.z-dn.net/?f=b)
Third term:
![- cd](https://tex.z-dn.net/?f=%20-%20cd)
Therefore the given polynomial has 3 terms.
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
Answer:
40
Step-by-step explanation:
So split it into two shapes. Two rectangles.
Rectangle 1 = 4 * 5 = 20
Rectangle 2 = 2 * 10 = 20
20 + 20 = 40
Answer:
x=-3
Step-by-step explanation:
x+9 = 3.2=6
x= 6-9=-3
10 feet.
Equation: a = v1/3 = 1000 1/3 = 10ft.
