1 answer:

6 0

The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: <span>(4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x</span>

Answer:

x and y = 0

the question looks weird and almost wrong because when you subtract the equations, you are left with nothing

Step-by-step explanation:

Multiply the top equation by 3 to make the -x a -3x instead.

Then do the top equation - the bottom equation

At this point you should be left with x

Answer:

$h = 12$

$x = 9$

$y= 16$

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

$A = \frac{1}{2} * 15 * 20$

$i.e\ height = 20$

$A = \frac{1}{2} * 300$

$A = 150$

Let the base of the triangle be 25.

So, the area is:

$A = \frac{1}{2} * 25 * h$

$i.e\ height = h$

$A = \frac{1}{2} * 25h$

Substitute $A = 150$

$\frac{1}{2}*25h = 150$

Solve for h

$h = \frac{150 *2}{25}$

$h = 6 *2$

$h = 12$

Considering the smallest triangle

$Hypotenuse = 15$

So:

$15^2 = h^2 + x^2$

$15^2 = 12^2 + x^2$

This gives:

$15^2 - 12^2 = x^2$

$81 = x^2$

Take square roots

$9 =x$

$x = 9$

Solving for y

$x + y = 25$

$y= 25 - x$

$y= 25 - 9$

$y= 16$

avanturin [10]

He made 3.75 gallons. There was 1/10 remaining, meaning each tenth was 6 cups. The entire thing is 10 tenths so you do 6(10) to get 60 cups. After converting to gallons by doing 60÷26, you get 3.75.
