Answer:
x + 4√(x + 2) + 6
Step-by-step explanation:
All we need to do is expand by using FOIL (First, Outside, Inside, Last):
x + 2 + 2√(x + 2) + 2√(x + 2) + 4
Then we combine like terms to get our final answer:
x + 2 + 4√(x + 2) + 4
x + 4√(x + 2) + 6
Answer:
15
Step-by-step explanation:
| -15 |
The absolute value means take the positive value of whats inside
| -15 | = 15
4(x-5)=3(x+5)
Multiply the first bracket by 4
(4)(x)=4x
(4)(-5)=-20
Multiply the second bracket by 3
(3)(x)=3x
(3)(5)=15
4x-20=3x+15
Move 3x to the other side
Sign changes from +3x to -3x
4x-3x-20=3x-3x+15
4x-3x-20=15
x-20=15
Move -20 to the other side
Sign changes from -20 to +20
x-20+20=15+20
x=15+20
Answer: x=35
Answer:
The number of the television sets that is model p is 12
Step-by-step explanation:
Here we have total number of television sold = 40
The model p televisions sold for $30 less than the model q televisions
That is $P = $q - $30
Therefore
Let the quantity of the model p sold be X
Let the quantity of the model q sold be X
Therefore
x + y = 40
Total cost of the television = 40 * 141 = $5640
Therefore, 120*x + 90*y = 5640
Plugging in x = 40 - y in the above equation we get
4800 - 30y = 5640 or
y = -28 and
x = 68
If we put y = 40 - x we get
30x + 3600 = 5640
If we put
120*x + 150*y = 5640.........(3)
we get
x = 12 and y = 28
Therefore, since the model p sold for $30 less than the model q, from the solution of equation (3) the number of the television sets that is model p = 12
