Answer:
1) 
2) Option C.
3) Option B.
Step-by-step explanation:
1. You must apply the Distributive property as following:

2. Now, you must distribute the negative sign, then you have:

3. Finally, you must add the like terms. Then you obtain the polynomial:

4. By definition, a polynomial that has two terms is classified as a binomial. Therefore, the answer is the option C.
5. The degree of a polynomial is determined by highest exponent of the variable. So, it is a polynomial of degree 2 (option B).
Answer:
A) 5
Step-by-step explanation:
6(2x+a)=12x+30
6*2x+6*a=12x+30
12x+6x=12x+30
6a=12x+30-12x
6a=30
a=30/6
a=5
Assume E represents the cost of an egg and T represents the cost of one piece of toast.
We can construct two equations :
2E + T = $3.00 - - - - - (a)
E + T = $1.80 - - - - - (b)
Subtract equation b from a:
E = $1.20 (The price of one egg)
To find out the price of one piece of toast, replace the price of one egg in equation b:
T = $1.80 - $1.20 = $0.60 (The price of one piece of toast)
