Mathematics
1 answer:
Svetach [21]3 years ago
4 0

Answer:

I think you mean: x^2 + 3x - 10, then

x^2 + 3x - 10

= x^2 + 5x - 2x - 10

=x(x + 5)  - 2(x + 5)

=(x - 2)(x + 5)

Hope this helps!

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 70 square feet. Find the
Vedmedyk [2.9K]

Answer:

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Let 'x' be the length of the rectangle

Given that the width is 3 feet shorter than the length

The width of the rectangle = x -3

Area of the rectangle = length × width

<u><em>Step(ii):-</em></u>

Area of the rectangle = length × width

                                  = x ( x-3)

Given that the area of the rectangle = 70 square feet

                       x ( x-3) = 70

              ⇒   x² - 3x - 70 =0

              ⇒  x² - 10 x + 7 x - 70 =0

             ⇒  x (x -10) +7( x-10) =0

            ⇒ ( x+7) ( x-10) = 0

           ⇒  x =-7 and x=10

<u><em>Final answer:</em></u>-

we choose x=10

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

64 = % 
X = of
100 = 100
  
48 X 100 = 4,800
64 X x = 64x 

64x / 64 = x
4800 / 64 =  75
