Answer:

(3/2, 0+), (-1, 0+)

Step-by-step explanation:

An exact "zero" of a polynomial is characterized by a point on the x-axis.  In this case the best approximation to that is the point (3/2, 0+); the next best approximation is (-1, 0+).  Note that neither of these two points actually lies on the x-axis, but that both are closer to the x-axis than are any of the other given points.

The perimeter of a basket ball court is 108 m and the length is 6 m long than twice the width. What are the length and the width
Gnoma [55]
Let's say

P = perimeter, L : Length and w : width

Then

P=2(L+w)=2L+2w=108

But 

L=6+2w

So

2L+2w=108\\2(6+2w)+2w=108\\12+4w+2w=108\\12+6w=108\\6w=108-12\\6w=96\\w=16

L=6+2w\\L=6+2(16)\\L=6+32\\L=38

We verify :

2L+2w=108\\2(38)+2(16)=108\\76+32=108\\108=108

Length = L = 38
Width = w = 16

Elina [12.6K]

Answer:

76

Step-by-step explanation:

A + B = 127

5.80A + 4.25B = 657.55

Solve with substitution.

5.80A + 4.25(127 − A) = 657.55

5.80A + 539.75 − 4.25A = 657.55

1.55A = 117.80

A = 76
