Suppose there is a rectangle with a width and length of x and y. The area would be xy.
A rectangle with width and length 2x and 2y would have an area of 4xy.
In essence, when you multiply the lengths by 2, the area multiplies by 2 SQUARED.
4(4(x+3)) = 16(x+3).
The ratio will be the same for any value of x because the area is still being multiplied by the same 2².
Answer:
x= -1/3 or x= -3/3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+6x−1=−5x−4
Step 1: Subtract -5x-4 from both sides.
6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)
6x2+11x+3=0
Step 2: Factor left side of equation.
(3x+1)(2x+3)=0
Step 3: Set factors equal to 0.
3x+1=0 or 2x+3=0
x= -1/3 or x= -3/3
