Okay so you basically assume f(x) is 0.
The positive quadratic formula (as a refresher) is x= (-b+√b∧2-4ac)/2a
By looking at the equation you can determine
a=1
b=2.6
c=-7.32
And plug these in to solve
-2.6+√6.76+7.32)/2

Once you solve the answer will be x=1.7

Find the linear equation with<br> Slope= 2/3<br><br> y-intercept = 1

beks73 [17]

Answer:

I believe the answer would be using the form of y= mx+b, b is y intercept and slope is m. It would end up looking like y= 2/3x+1

Step-by-step explanation:

I think this is how a linear equation looks like but I'm a little rusty. If you have notes it probably says what I already stated. Good luck! :)

The width of a human hair is 2 x 10-5 meters. The width of a piece of sand is 1.5 x 10¹ meters.

Elena L [17]

The difference in the widths, in meters, of the human hair and the piece of sand is $1.4998*10^{-1}$ m.

It is given in the question that:-

Width of a human hair = $2*10^{-5}$ m

Width of a piece of sand = $1.5*10^{-1}$ m

We have to find the difference in the widths, in meters, of the human hair and the piece of sand.

We know that,

Difference between the widths = Width of a piece of sand - Width of a human hair

Hence, we can write,

Difference between the widths = $2*10^{-5}$ m - $1.5*10^{-1}$ m

We can write,

$1.5*10^{-1}=15000*10^{-5}$

Hence,

Difference between the widths =

$15000*10^{-5} - 2*10^{-5}= 14998*10^{-5} = 1.4998*10^{-1}$ m

Find the product of (5x+4)(5x-4)

nydimaria [60]

Answer:

25x² - 16

Step-by-step explanation:

Given

(5x + 4)(5x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

5x(5x - 4) + 4(5x - 4) ← distribute parenthesis

= 25x² - 20x + 20x - 16 ← collect like terms

= 25x² - 16
