Simplify the expression -2x^2(4x − 3).<br> -8x3 − 6x2<br> -8x3 + 6x2<br> 8x3 − 6x2<br> 8x3 + 6x2
Digiron [165]
To simplify the expression we are going to use the distributive property of multiplication: a(b+c)=ab+ac.
We can infer from our problem that a=-2x^2, b=4x, and c=-3. So lets apply the property to simplify our expression:
-2x^2(4x-3)=(-2x^2)(4x)+(-2x^2)(-3)
(-2x^2)(4x)+(-2x^2)(-3)=-8x^3+6x^2

We can conclude that the correct answer is <span>-8x3 + 6x2</span>

Please help will give 20 points to right answers (will give brainliest to very first correct answer) Tom walks 3.2 km every morn
nignag [31]
For this case we have the following conversions:
 1 mile = 1,609 km&#10;&#10;1 mile = 5,280 feet
 We must apply the conversions to move from kilometers to feet.
 We have then:
 (3.2) * (1 / 1,609) * (5280) = 10500.93226&#10;
 Rounding off we have:
 10501 feet
 Answer:
 
there are 10501 feet in 3.2 km

Find the sum and the product of the roots of the equation:<br><br> x^2−37x+27=0
lawyer [7]

Answer:

Sum of the Roots = 37

Product of the Roots = 27

Step-by-step explanation:

Here, the given expression is  x^{2}  - 37x + 27 = 0

Now the general Quadratic Equation is of the form:

ax^{2}  + bx + c = 0

Here, Sum of the Roots = -(\frac{b}{a} )

and the Product of the Roots =  (\frac{c}{a} )

So, comparing the general equation with the given equation, we get:

a = 1, b = -37 and c = 27

So, Sum of the Roots = -(\frac{-37}{1} )  =  37

and the Product of the Roots =  (\frac{27}{1} ) = 27
