Let

x = number 8043

y = number 9

z = the product of 8043 and 9

z = x*y

We substitute

z = (8043)*(9)

z = 72387

Solve for b: A= (h(a+b))/2

tresset_1 [31]

A= (h(a+b))/2

multiply each side by 2

2A = (h(a+b))

divide each side by h

2A/h = a+b

subtract a from each side

2A/h -a = b

The perimeter of a rectangular building is 1200 feet. The width of the building is 2 feet less than three times the length. What

juin [17]

Given:

The perimeter of a rectangular building is 1200 feet.

The width of the building is 2 feet less than three times the length.

To find:

Width of the building.

Solution:

Let length of the building be x.

Then, width = 3x-2

We know that,

$Perimeter=2(length +width)$

$1200=2(x+3x-2)$

$1200=2(4x-2)$

$1200=8x-4$

Add 4 on both sides

$1204=8x$

Divide both sides by 8.

$\dfrac{1204}{8}=x$

$150.5=x$

Now,

$Width=3x-2$

$Width=3(150.5)-2$

$Width=451.5-2$

$Width=449.5$

Therefore, the width of the building is 449.5 feet.

Select the quadratic equation that has roots x=8 and x=-5

stellarik [79]

Step-by-step explanation:

Since, x=8 and x=-5 are the roots.

Therefore, (x - 8) & (x - 5) will be factors.

Hence, required quadratic equation can be given as:

$(x - 8)(x - 5) =0 \\ \\ \therefore {x}^{2} + ( - 8 - 5) x+ ( - 8) \times ( - 5) = 0 \\ \\ \therefore {x}^{2} + ( - 13) x+ 40= 0 \\ \\ \huge \red{ \boxed{ \therefore {x}^{2} - 13x+ 40= 0 }} \\ is \: the \: required \: quadratic \: equation.$
