Answer:
Radical expressions must be simplified before adding or subtracting so that you are combining “like terms”. In the same way that 2x2 and 3x cannot be combined because they are not like terms, terms involving radicals cannot be combined unless the value under the radical is the same for both terms.
$12.75-$11.25= $1.50, $9.75-$1.50= $8.25 his little brother should get $8.25 hope it helps

3.

Step-by-step explanation:
1. The given polynomial is

We need to factor the second part to get:

We factor y-5 to obtain:

2. We have

We again factor -1 from the second part to get:

We now factor x-y to get:


3. We have

We factor negative 1 from the first part to get

We now factor b-3 to get:

We now simplify to get:

Answer: 1,811 square foot
Step-by-step explanation:
Hi, to answer this question we have to solve the equation given, by substituting P = 4,148 and f=190 in the equation.
P = 1.85s + 4.2f
4,148 = 1.85s +4.2 (190)
Solving for s:
4,148 = 1.85s +798
4,148-798 =1.85s
3,350 = 1.85s
3,350/1.85 =s
s = 1,810.81 = 1,811 square foot (rounded)
