Answer:
9
Step-by-step explanation:
The standard form of an equation is
In the question, we have the following formula
To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)
Finally we subtract 1 from both sides (since we need the number on the right side)
Hence, 4. is the correct answer.
Answer:
Length of the room is 180 ft
Step-by-step explanation:
We have a rectangular room with dimensions:
width = 70 ft and length "x" (unknown)
Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:
2*70 + 2*x = 500
140 + 2*x = 500
2*x = 500 - 140
2*x = 360
x = 360/2
x = 180 ft
Its same as powers of a whole number.
Lets take example
(1/2)²=1/2×1/2=1/4
We can write it in a different way (0.5)²=0.5×0.5=0.25
