Answer:
x=y^2
Step-by-step explanation:
cause the definition of equation is one x correspond to one y,but one y can correspond to 2 x,
the picture I give to you a x correspond to 2 y

Required
Which group forms a rectangle of
First, calculate the area of the big rectangle
Next, calculate the area of each rectangle A to E.
Then consider each option.
(a) 3E + 2B
(b) A + B + C + D
(c) 2C + 2D + 2B
(d) A + 4B
(e) E + C + D + 3B
Recall that:
Only options (b) and (d) match this value.
<em>Hence, options (b) and (d) are correct</em>
A) The greatest rectangular area will be the area of a square 10 m on each side, 100 m^2.
b) The new dimensions will be 11 m × 11 m.
.. The new area will be (11 m)^2 = 121 m^2.
c) The area was increased by 121 m^2 -100 m^2 = 21 m^2, or 21%.
d) Yes, and no.
.. If you increase the dimensions by 10%, the area will increase by 21%.
.. (40 m)^2 = 1600 m^2
.. (44 m)^2 = 1936 m^2 = 1.21*(1600 m^2), an increase of 21% over the original.
.. If you increase the dimensions by 1 unit, the area will increase by (2x+1) square units, where x is the side of the original. For x≠10, this is not 21 square units.
.. (41 m)^2 = 1681 m^2 = 1600 m^2 +(2*40 +1) m^2 = 1600 m^2 +81 m^2

Answer:
17.1 liters
Step-by-step explanation:
Since one gallon equals 3.8 liters.
We can multiply 4.5 gallons by the approx. 3.8 liters
4.5 * 3.8 = 17.1 liters
