Answer:

Acute

Step-by-step explanation:

26^2 + 12^2 = 18^2

676 + 144 = 324

820 = 324

Since 324 is smaller, this triangle is acute

If x =2/3, what is the value of the following expression? X^3 x 3 divided by 2/9 + 9x - 7-6x
Damm [24]
This is a basic algebraic equation

And will be using PEMDAS to solve

P: Parentheses
E: exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction

If you are unaware of PEMDAS this is the order at which you solve algebraic equation. So start from “P” and end with “S”


X= 2/3

2/3^3 Times 3 Divided by 2/9 + 9(2/3) - 7 - 6(2/3)

Now, personal I’d choose to convert fractions to decimals to simplify solving the equation. I doubt this is the only way to solve for the equation but I find this is the easiest

To convert a fraction to decimal you divide the numerator by the denominator.

So 2/3 is 0.666667
And
That means 2/9 is 0.222222

0.666667^3*3/0.222222+9(0.666667)-7-6(0.666667)

Making you answer roughly -0.999989

Hope this helps, but I’m not sure if this is completely right or not

I have a question about polynomial division it is in the picture
Cloud [144]

To answer this question, we have to do the long division process for polynomials. We can do the operation as follows:

To do this division process, we have:

1. Divide the first term of the dividend by the first element of the divisor. They are:

\frac{-4x^3}{4x^2}=-x

2. Now, we have to multiply this result by the divisor, and the result will change its sign since we have to subtract that result from the dividend as follows:

-x\cdot(4x^2_{}-4x-4)=-4x^3+4x^2+4x

And since we to subtract this result from the dividend, we end up with:

-(-4x^3+4x^2+4x)=4x^3-4x^2-4x

3. Then we have the following algebraic addition:

\frac{\begin{cases}-4x^3+24x^2-15x-15 \\ 4x^3-4x^2-4x\end{cases}}{20x^2-19x-15}

4. Again, we need to divide the first term of the dividend by the first term of the divisor as follows:

\frac{20x^2}{4x^2}=5

5. And we have to multiply 5 by the divisor, and the result will be subtracted from the dividend:

5\cdot(4x^2-4x-4)=20x^2-20x-20

Since we have to subtract this from the dividend, we have:

-(20x^2-20x-20)=-20x^2+20x+20

6. And we have to add this algebraically to the dividend we got in the previous step:

\frac{\begin{cases}20x^2-19x-15 \\ -20x^2+20x+20\end{cases}}{x+5}

And this is the remainder of the division, x + 5.

As we can see from the division process, we got as:

1. The quotient: -x + 5

q=-x+5

2. The remainder: x + 5.

R=x+5

Since we have that the dividend = divisor * quotient + remainder.

Therefore, the result for this division is:

-4x^3+24x^2-15x-15=(4x^2-4x-4)\cdot(-x+5)+(x+5)
