A = 2.76 x 10^12 = 27600000000
w = 4.6 x 10^5 = 460000
w x l = A
2760000000000/460000 = 6000000
l = 6000000
(w x 2) + (l x 2) = perimeter
((4.6 x 10^5) x 2) + ((6.0 x 10^6) x 2) = 12920000

ANSWER: perimeter = 129.2 x 10^5

Find the specified element in the inverse of the given matrix
JulijaS [17]
What is the given matrix?
you didn't show a matrix.
the components of the matrix are the elements.
and the elements of the inverse matrix are the elements of the inverse matrix
1) 
so if matrix A is  1   4  1   
                          2   5  2
                          3   6  3
2)
14114
25225
36336

3)
15 24 12
15 12 24
4)
[A]=(15+24+12=51)-(15+12+24=51)
[A]=0
5)
    52    23   25
    63    23   36

    41    11   14 
    63    33   36

    41    12    14
    52    12    25
6)

    15-12   6-6   12-15

     12-6    3-3    6-12

      8-5     2-2     5-8


7) 
     3    0   -3

     6    0   -6

     3    0   -3
 8) 
     (+)3    (-)0   (+)-3

     (-)6    (+)0   (-)-6

     (+)3    (-)0   (+)-3
=

    3  0  -3
   -6  0   6
    3  0  -3

9)
        3 -6  3
N=   0  0  0
       -3  6 -3
10) the inverse of [A]= 1/|A|*[N]
which is in this case ⁻A= 0
because |A|=0

1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters
Bond [772]

Answer:

x\leq 1.78

Step-by-step explanation:

We are given that

Width of pool, b=4.5 m

We have to find the inequality which  represents the possible lengths of the wading pool.

Let x be the length of wading pool

We know that

Area of rectangle=length\times breadth

According to question

Using the formula

4.5x\leq 8

Divide by 4.5 on both sides we get

x\leq\frac{8}{4.5}

x\leq 1.78

Yaaay even more algebra
Anika [276]

Answer:

f(x) = 3x-1

g(x) = x+2

Find (f-g)(x), this means we need to subtract g from x.

(3x-1) - (x+2)

Subtract the like terms:

3x -x = 2x

-1 -2 = -3

Combine them to get 2x-3

The answer is B.

Brainliest would be much appreciated!
