The width of a rectangle is 1 units less than the length. The area of the rectangle is 56

Mathematics

Answer:

Width = 7 units

Step-by-step explanation:

Length = x units

Width = (x -1) units

Area = 56 square units

length * width = 56

x * (x - 1) = 56

x*x - x*1 = 56

x² - x  - 56 = 0

x² -8x + 7x - 7*8 = 0

x(x - 8) + 7(x - 8) = 0

(x - 8)(x + 7) = 0

Here, (x +7) is ignored because measurement will not  in negative.

x - 8 = 0

x = 8

Length =  8 units

Width = 8-1 = 7 units

Answer:

$94.05

Step-by-step explanation:

Original price of jeans=$95

Discount=10%

New price=(100% - 10%) of $95

=90% × 95

=90/100 × 95

Total amount paid for the jeans= sales tax + new tax

=$8.55 + $85.5

=$94.05

To make a square for x²+bx=c, add( \frac{1}{2} b)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
