All you have to do is multiply 10 and 40. Then multiply the other 10. 40 x 10 = 400.

What is the discriminant of the quadratic equation 2x² - x - 3=0?
Tamiku [17]

The given quadratic equation is

2 {x}^{2}  - x - 3 = 0

comparing with

{ax}^{2}  + bx + c = 0

We get ,

a = 2 \\ b =  - 1 \\ c =  - 3

formula :

D =  {b}^{2}  - 4ac \\  \\ D =  {( - 1)}^{2}  - 4 \times 2 \times ( - 3) \\  \\ D = 1 - ( - 24) \\  \\D  = 1 + 24 \\  \\D  = 25.

Discriminant of given quadratic equation is 25 .

Help on area of composite figures
balandron [24]
 break it up into simpler shapes. See the photo.
There is:
trapezoid
A = 0.5(3.2+6.5)4.5
= 21.825

triangle
A = 0.5(2.7)4.5
= 6.075

rectangle
A = 1.8(4.5)
= 8.1

Total Area = 21.825 + 6.075 + 8.1

How do u do this?? What’s the answer???
V125BC [204]

Answer:

A. c = 0.31b

Step-by-step explanation:

$7.44 = 24 juice bottles

[Divide by 24 on both sides]

$0.31 = 1 juice bottle

The cost is equal to the amount per juice bottle times the number of juice bottles, so:

c = 0.31b

(A trick to use when you don't know the answer: If there are multiple answers with the same numbers but the decimal places are in different places, it is probably one of those answers.)
