Answer:

b bn = 7 (5)^ (n-1)

Step-by-step explanation:

First we need to find the ration

Take the second term and divide by the first term

35/7 = 5

The formula for the sequence is given by

an = a0 (r) ^(n-1)

where a0 is the first term, r is the ratio

an = 7 (5)^ (n-1)

Team one had twice as many workers as team two. The number of workers in team one is reduced by 5 and the number of workers in t
inessss [21]

let

x-------> workers in team one initially

y-------> workers in team two initially

we know that

x=2y-----> equation 1

(x-5)=(y-2)+7-----> x-5= y+5----> x=y+10---------> equation 2

equate equation 1 and equation 2

2y=y+10-----> y=10

x=2*10------> x=20

Team 1 now has 20-5 = 15 members 
Team 2 now hase 10-2 = 8 members

The equation A = x(x-4) describes the area, A, of a rectangular flower garden, where x is the width in feet.
BabaBlast [244]

Answer:

The flower garden width would be 6 ft

Step-by-step explanation:

A = 12 ft^2 = x(x + 4) becomes:

x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0

Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16

Taking the square root of both sides yields x + 2 = ±4.

In this context only a positive x value makes sense:  x = 2 + 4  =>  x = 6.

The flower garden width would be 6 ft.  The other dimension would be 6 - 4, or 2, ft.
