Answer:
the area will be increased by 44%
Step-by-step explanation:
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.
Answer: (C) 13,120
<u>Step-by-step explanation:</u>
Given the sequence {4, 12, 36, 108, ... , 8748} we know that the first term (a) is 4 and the ratio (r) is 
Input the values above into the Sum formula:

5x+2y = 5.84 is the equation for maddi.
2x+ 8y =10.40 is the equation for stephen.
set them equal and then cancel them out! if you do that you can plug it into the part 2 equation which is
2x+4y+z=4.07
The correct answer is <span>y = -x(x - 1)(x + 2).</span>
