Please help me with this
ElenaW [278]

Answer: a=4, b=-8, c=-3

Step-by-step explanation: This equation isn't in standard form. To get it there, subtract -3 from both sides. This gets you an equation of 4x^2-8x-3.

The standard form is ax^2+bx+c.

A is the number before x^2 (4). B is the number before x, and since it's subtracted it's negative (-8). C is the last number, and since it's subtracted it's negative (-3).

A salt modure has 7 parts water and 1 part salt Suppose another part of salt is added What is the new ratio of salt
Sunny_sXe [5.5K]

Answer:

14:2 - 14 parts water and 2 parts salt

Step-by-step explanation:

The original ratio was 7:1. So, that means if you added another part to the salt it would make 2. That means that the 7 parts of water would become 14 parts. Since the ratio of the salt part was doubled from 1 to 2, you would have to do the same with the water ratio part. Hoped this helped!

jeyben [28]

Find the volume of 1 car by multiplying the length by the width by the height:

Volume of 1 car = 20 x 10 x 10 = 2000 cubic feet.


Now multiply the volume of 1 car by the total number of cars:

2000 x 100 = 200,000 cubic feet total.
