1)  9x + 2 = x + 5  ---> 9x + 2 = 6

subtracted X from one side but not the other

2) 3(x-4) + 5 = 12  ---> 3x + 4 + 5 = 12

didn't distribute correctly: 3(x-4)

multiplied the X by 3 but not the -4

Brainliest to correct answer, hurry please!
omeli [17]

company A :

30,000 + 0.03(37499) = 31124.97...sales less then 37500

30,000 + 0.03(37501) = 31125.03....sales exceed 37500

30,000 + 0.03(249000) = 37470 ...sales less then 250000

30,000 + 0.03(251000) = 37530....sales exceed 250000


company B :

25,000 + 0.05(37499) = 26874.95...sales less then 37500

25,000 + 0.05(37501) = 26875.05...sales exceed 37500

25000 + 0.05(249000) = 37450...sales less then 250000

25,000 + 0.05(251000) = 37550...sales exceed 250000


so i believe your answer is option b,

company A pays better when sales are less then 250,000, but company B pays better when sales exceed 250,000 <==

Sliva [168]

Answer:

The length of the long side of the rectangle is 38 ft.

Step-by-step explanation:

If we test out all possible factors, we will see that 15 x 38 is the most fitting.  

Perimeter: 15 + 15 + 38 + 38 = 106 ft.

Area: 15 x 38 = 570 square ft.

38 ft. is the measurement of the long side and 15 ft. is the measurement of the smaller side.
