PL HELP ME I HAVE A TEST IN THE MORNING WHOEVER ANSWERS CORRECTLY GETS BRAINLIEST! 1. How would we name the polynomial below? Think about degree and number of terms.
x^4 + 3x^2 - x

2. Simplify by adding
(x + 4) + (2x + 7)

3. Multiply
3x^2(5x^3)

4. Divide
8x^3y^5 / 4x^2y^3

2. 3x + 11

3. 15x^5

Step-by-step explanation:

2. Simplify by adding

(x + 4) + (2x + 7)

= x + 4 + 2x + 7

= 3x + 11

3. Multiply

3x^2(5x^3)

= 3 (5x^2 x^3)

= 3 (5x^2+3)

= 15x^5

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
