1. A polynomial means it has more than one term.
a. has 4 terms
b. has 1 term (not a POLYnomial)
c. has 3 terms
d. has 2 terms
2. The first word in a polynomial description tells the degree (max amount of exponents) of the expression, and the second word tells how many terms it has.
a. This answer means it's maxed exponent is to the fourth power, which it's not. (WRONG)
b. This answer means that it has a max exponent to the third power, which is true, and it also says it has three terms, which is also true. (CORRECT)
3. You must combine like terms in this polynomial.
=> 14x^2 - 6x^2 =8x^2
=> 5x + 2x = 7x
=> -8
d. This answer combines all the terms correctly.
4. To simplify this equation, you must first distribute the negative to all of the second equation.
(4x^2 -3x+2) + (-2x^2-5x+7)
Now, combine like terms.
=>4x^2 - 2x^2 = 2x^2
=>-3x - 5x = -8x
=>2 + 7 = 9
d. This answer simplifies it correctly
For this case we have an expression of mixed numbers:

Rewriting the expression we have:

Remember that equal signs are added and the same sign is placed.

Answer:

-9, -3 is the answer to your problem.
Answer:
They have equal ticks and angles. They are congruent because they are equal in all sides and angles.
Step-by-step explanation:
Answer:
i)vertical
ii)horizontal
iii)oblique
Step-by-step explanation:
When an equation is just x=a number, it is a horizontal line.
When the equation is just y=a number, it is a vertical line.
If the equation is the full y=mx+b, it is oblique.
2x=5
x=2.5
vertical
y+2=-1
y=-3
horizontal
x+y=3
y=-x+3
oblique
