Add the following polynomials, then place the answer in the proper location on the grid.

aivan3 [116]

Answer:

$x^3 - 6x + 2$

Step-by-step explanation:

The given polynomials can be added together by adding like terms together as shown below:

=> Add together, the coefficient of all terms that have the power of 3.

$(2x^3) + (x^3) + (-3x^3)$

$2x^3 + x^3 - 3x^3$

$3x^3 - 3x^3$

$x^3$

=> $(-4x^2) + (6x^2) + (2x^2)$

$-4x^2 + 8x^2$

$4x^2$

=> $(6x) + (-8x) + (-4x)$

$6x - 8x - 4x$

$-6x$

=> $(-3) + (12) +(-7)$

$-3 + 12 - 7$

$2$

The answer = $x^3 - 6x + 2$

Answer:

A would be 150 times.

Step-by-step explanation:

I can't see the options for Part B so i cant help with that sorry. I think A would be 150 times though because with numbers 1-10, half of them are even and half of them are odd and half of 300 is 150.

Find the value of t in the diagram

12345 [234]

In a trapezoid, with bases $b$ and $B$ and height $h$ , the area is given by

$A = \frac{(B+b)h}{2}$

In your case:

$B = BC = 3t$

$b = AD = t$

$h = AB = t$

so, the formula becomes

$A = \frac{(3t+t)t}{2} = \frac{4t^2}{2} = 2t^2$

Since the area is $50 \text{cm}^2$ , we have

$2t^2 = 50 \iff t^2 = 25 \iff t = 5$
