Answer:

36

Step-by-step explanation:

Width = x

Length = 4x

Perimeter = Width + Width + Length + Length (Because there are four sides; two sides are the widgth and two sides are the length)

30 (because 30 is given as the perimeter) = x + x + 4x + 4x

30 = 10x

x = 3

Width = 3

Length = 4(3) = 12

Area = Width * Length

Area = 3 * 12 = 36

Plz help<br> x−(73+27)=400
Viktor [21]

First solve for parenthesis

73 + 27 = 100

x - 100 = 400

Isolate the x. Add 100 to both sides

x - 100 (+100) = 400 (+100)

x = 400 + 100

x = 500

500 is your answer for x

hope this helps

First lets find out how much sugar was needed

1/4=1/4=2/4

2/4+1/6=6/12+2/12=8/12

8/12 simplified=2/3

2/3 of the sugar is needed

3/4-2/3=9/12-8/12=1/12

1/12 of the sugar was left

A geometric series has the third term 36 , and sixth term 972 . Find the first term of the series
ladessa [460]

Answer:

the first term is 4

Step-by-step explanation:

Given

G(3) = 36

G(6) = 972

Solution:

General formula for geometric series

G(x) = AB^x

From given data: G(6)/G(3) = 972/36 = 27

From formula: G(6)/G(3) = AB^6/(AB^3) = B^3

Therefore

B^3 = 27

B=3

Hence

G(1) = AB^1 = AB^3/B^2=36/3^2=36/9=4

Ans: the first term is 4
