I have a rectangle that is 2 1/2 feet long and 1 1/3 feet wide. What is the area of the rectangle? Please show work

I cant really attach a picture but this is the answer so you turn 2 1/2 into a improper fraction which is 5/2. then you multiply 11/3*5/2. And that equals 55/6. and then turn it into a whole number and it equals 9.16..

Factor the quadratic expression in the equation y=2x^2+28x+96 and use the factors to find the zeros of the equation. Then, use t

gavmur [86]

Answer:

$x=-7$

Step-by-step explanation:

We have been given an equation $y=2x^2+28x+96$ . We are asked to find the zeros of equation by factoring and then find the line of symmetry of the parabola.

Let us factor our given equation as:

$2x^2+28x+96=0$

Dividing both sides by 2:

$x^2+14x+48=0$

Splitting the middle term:

$x^2+6x+8x+48=0$

$(x^2+6x)+(8x+48)=0$

$x(x+6)+8(x+6)=0$

$(x+8)(x+6)=0$

Using zero product property:

$(x+8)=0\text{ (or) }(x+6)=0$

$x+8=0\text{ (or) }x+6=0$

$x=-8\text{ (or) }x=-6$

Therefore, the zeros of the given equation are $x=-8\text{ (or) }x=-6$ .

We know that the line of symmetry of a parabola is equal to the x-coordinate of vertex of parabola.

We also know that x-coordinate of vertex of parabola is equal to the average of zeros. So x-coordinate of vertex of parabola would be:

$\frac{-8+(-6)}{2}=\frac{-14}{2}=-7$

Therefore, the equation $x=-7$ represents the line of symmetry of the given parabola.

What is the volume of the right prism?

a_sh-v [17]

Answer: 720

Step-by-step explanation: to solve this problem, we do 15*8*12= 1440

this shape is half of that though, so we do 1440/2= 720, so the answer is 720

How to solve 3 over 8 = x over 24

Ivan

Multiply each side of your equation by 24.

Then one side of it will be 'x',and the other side will be the value of 'x'.
(It will be in the form of a fraction, which you may want to simplify.)
