Step-by-step explanation:
Force = pressure * area
= 200 * 3.7
= 740 N
first off, let's notice the parabola is a vertical one, therefore the squared variable is the x, and the parabola is opening upwards, meaning the coefficient of x² is positive.
let's notice the vertex, or U-turn, is at (-2, 2)
Let the width =x
length = 6x
p=14x
28=14x
x=2
Answer:
to estimate the sum you round to the closest number like 38 is closest to 40 so you just say you total is $40.00
difference is when say you have 30 dollars and you spend 10 the difference is 10 dollars
