because if you do the math its easy
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
Answer:
8 hours
$480
Step-by-step explanation:
Let us assume the hours be x
There should be two equations
For Plumber A = 60x
For Plumber B = 40 + 55x
Now in order to considered the cost to be the same we equate these two equations
60x = 40 + 55x
5x = 40
x = 8 hours
Now the total cost for plumber A is
= 480
And, the total cost for plumber B is
= 40 + 55(8)
= 480
hence, the total cost is $480
<span>2(3x + 7) = -22
Use distributive property
6x+14=-22
Subtract 14 from both sides
6x=-36
Divide 6 on both sides
Final Answer: x=-6</span>
Answer:
Step-by-step explanation:
The absolute value of a number is how far away it is from 0 on the number line. Even though 
is a negative number, the absolute value wouldn't be , because distance can't be negative. Hence the absolute value of is .
