Answer:

single term
sum of 4 terms, some of which can be expanded further

Step-by-step explanation:

1. 3x

This is a single term with one variable of the first degree.

2. 4x + 9(2x + 1) x² + 6(-2x + 1) - 3(7 + x?)

This is a sum of 4 terms, some of which can be expanded:

4x
9(2x+1)x^2 ⇒ 18x^3 +9x^2
6(-2x +1) ⇒ -12x +6
-3(7+x?) ⇒ -3x? -21

The expression can be simplified by combining like terms.

Is it possible to draw a triangle with numbers 5,6,11

Tatiana [17]

Answer:

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is $a^2 + b^2 = c^2\\$ .

11 is the bigger side in this case, so our formula would go like this: $5^2 + 6^2 = 11^2\\$ .

We now calculate to see if this is true.

25 + 36 $\neq$ 121

Therefore, the answer is wrong.

Which of the following is 38/6 converted to a mixed number

Monica [59]

6 goes into 38 6 times (6 * 6 = 36). We can bring out a whole number of 6 into our mixed number. Now, we have 2/6 left over. That can be reduced to 1/3. Your mixed number is $6\frac{1}{3}$

How do I work this out?

pentagon [3]

1. 1/4(x+3)=12=X+3-12*4/4=X-45/4. Then, x-45/4=0. So, 1. X=45. 2. x+4/3=12=3x-32/3*3=0*3. 3x-32=0. You add 32 to each sides. 3x=32. x=32/3. Therefore, 1. x=45 and 2. x=32/3
