The answer is d. Once an expression has been factored, use the distributive property to expand the expression. The expanded expression should be the original expression.

the rectangle shown has a perimeter of 56 cm and the given area. it's length is 8 more than three times it's width. write and so

stiv31 [10]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Assume width of rectangle be " x ", length = 3×width + 8 = 3x + 8 ~

Now, Perimeter of rectangle is :

$\qquad \sf \dashrightarrow \:2(l + w) = 56$

$\qquad \sf \dashrightarrow \:2(3x + 8 + x) = 56$

$\qquad \sf \dashrightarrow \:2(4x + 8) = 56$

$\qquad \sf \dashrightarrow \:4x + 8 = 56 \div 2$

$\qquad \sf \dashrightarrow \:4x + 8 = 28$

$\qquad \sf \dashrightarrow \:4x = 28 - 8$

$\qquad \sf \dashrightarrow \:x = 20\div 4$

$\qquad \sf \dashrightarrow \:x =5 \: cm$

Hence, width = x = 5 cm

$\qquad \sf \dashrightarrow \:l = 3w + 8$

$\qquad \sf \dashrightarrow \:l = 3(5)+ 8$

$\qquad \sf \dashrightarrow \:l = 15+ 8$

$\qquad \sf \dashrightarrow \:l =23 \:cm$

And, length = 26 cm

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of . A. B. C. D.

maksim [4K]

Answer:

$\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]$

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is $ar^{n-1}$
