Answer:
Step-by-step explanation:
Answer:
x = 3 and x = 7
Step-by-step explanation:
Equate the product of the factors to zero, that is
(x - 3)(x - 7) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y.
3x + 2y = 16
Given the sizes of the room, the relation should be that,
x = 2y
Solving the equation,
3(2y) + 2y = 16
y = 2
Therefore x is equal to 4 gallons.
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.
<span>x^2 +5x Should be your answer because:
</span><span>Rectangle area=width * length </span>
<span>Width= x </span>
<span>Length=x+5 </span>
<span>Rectangle area=x*(x+5)=x^2 + 5x,
I hope this helps!</span>
