Width of the rectangle is 9 units
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then the length = x - 3. Find dimensions of the rectangle if its area = 54 sq. units
Area of the rectangle = length × width
⇒54 = x (x - 3)
⇒54 = x² - 3x
⇒x² - 3x - 54 = 0
⇒x² + 6x - 9x - 54 = 0 (Using Product Sum rule to factorize)
⇒x(x + 6) - 9(x + 6) = 0
⇒(x + 6)(x - 9) = 0
⇒x = -6, 9 (negative value is neglected)
x = 9 units
Y=mx+b...............................................................................................
Answer:
since x is a multiple of 5
similarly y is multiple of 3
so 3 6 <u>9</u><u> </u>12
Artaud is 12. To get this answer you first have to work backwards. So subtract 40 from 28 and you get -12. Then find the opposite of that which is 12.
The shirt will end up costing $9 after sale and tax is put on so if you give the cashier a $10 bill and the cost is $9, you will get $1 in change back.
