1. Find the GCF of 3x3y5z and 21xy3z4. 2. Is √(x) – 7 a polynomial? Explain why or why not.

3. Is x5 + x2 + x a polynomial? Explain why or why not.

4. What is the degree of x5 + x2 + x? How do you know?

5. Simplify (3x3 + 8x2 – 2x + 4) + (6x2 + 4x + 4).

6. Simplify (5x4 – 3x2 + 7x – 10) – (2x4 – 3x3 + 6x – 17)

7. Multiply 9x3(4x + 7)

8. Multiply (3x – 1)(5x – 9)

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
