Answer:
x(3x+14)
Step-by-step explanation:
what do those terms share? they share the letter "x"
therefore we multiply x by 3x^2/x + 14x/x
3x^2/x = 3x and 14x/x = 14
22-7-7-7=1 this will show that you can subtract 7 three times from 22 and have a remainder of 1.
The answer is B. you multiply 300 and 15% and it gets you 45 that’d save you money compared to the second incentive
1/5(x-y) = 1
x+y = 9
x-y = 5 (x5)
x+y = 9
First you want to create both equations so at least one of the variables (x or y) are the same in both equations, so that is why I multiplied the top one by 5, you multiply the whole equation (both sides)
2x = 14
x = 7
Then you either Plus or minus one from the other, I plused the top one onto the bottom one, then solved for x
7 + y = 9
y = 2
Then put x back into one of the first two equations to get Y
Answer:
$420
Step-by-step explanation:
First convert the room measurements from feet to yards to match the unit of measure of the carpet.
Room size is 12 feet by 21 feet.
3 feet = 1 yard.
12/3 = 4 yards
21/3 = 7 yards
4 yards times 7 yards = 28 square yards
28 square yards times $15 per square yards = $420.
