Answer:

  • B. a₁ = -6, aₙ = aₙ₋₁ + 4

Step-by-step explanation:

<u>From the given sequence we see that:</u>

  • Common difference is 4

<u>Find the first term:</u>

  • a₁ + 3*4 = a₄
  • a₁ + 12 = 6
  • a₁ = -6

<u>The recursive formula for this sequence is:</u>

  • a₁ = -6, aₙ = aₙ₋₁ + 4

Correct choice is B

The length of a rectangle is twice its width. if the perimeter is 72 meters, find the length and width of the rectangle
madam [21]
Length(l)= 2w
width(w)= w

Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units

find length:
l=2w
l= 2(12)
l= 24 units

Answer:
The length of this rectangle is 24 units and the width is 12 units.

A washer and dryer cost a total of $924. The cost of the washer is two times the cost of the dryer. Find the cost of each item.
marshall27 [118]

Answer:

Washer = $616, Dryer = $308

Step-by-step explanation:

When something is twice the cost of something else but add up to be a total number that means 2/3rds is one item and 1/3 is the other.

924 / 3 = 308

308 * 2 = 616

308 + 616 = 924

What is the width of this shape
77julia77 [94]
We see that the area is 159 3/8 and the length is 18 3/4.

Because the area is the length*width, to find the width, we must divide the area by the length.

Think of it this way:
A = l*w

Divide l on both sides:
\frac{A}{l} = w

And w is what we're looking for.
So, divide 159 3/8 by 18 3/4. 

You should get that the width is 8.5 feet :)
