Answer:

12x+4

Step-by-step explanation:

(6x+2)^2=36x^2+24x+4

(36x^2+24x+4)/3x+1=2(6x+2)=12x+4

Answer:

L = 12x + 4

Step-by-step explanation:

(see diagram for reference)

the area of the square

= (6x+2) (6x+2)  (factor out 2 from each parentheses)

= (2)(3x+1)(2)(3x+1)  (group like terms and simplify)

= 4(3x + 1)²

the area of the rectangle,

= (3x+1) (L)

It is given that the square and the circle have the same area, hence we equate the areas of square and rectangle:

4(3x + 1)² = (3x+1) (L)     (divide both sides by 3x+1)

4(3x + 1) = (L)   (rearranging and expanding the parentheses)

L = 12x + 4

Hope this helps

A man bought a pair of jeans for $23.00 a shirt for $14.00 and two ties for $7.98 each. What was the total cost of his clothing
Anna35 [415]

Answer:

$52.96

Step-by-step explanation:

To find the total cost of his clothing, add up the prices of everything he bought.

Jeans: $23.00

Shirt: $14

Ties: 2 ties for $7.98 each.

Each tie costs $7.98, and the man bought two ties. Therefore, multiply 2 and $7.98

2*$7.98 = $15.96

Add all the prices together.

jeans + shirt + ties

$23 + $14 + $15.96

$37 + $15.96

$52.96

The total cost of his clothing is $52.96

Work this out by giving your answer as a fraction 2/3 - 1/2
suter [353]

When subtracting fractions, you need to make sure the denominators are the same. In 2/3 - 1/2, the denominators are different. To make them the same, find the least common denominator. In this case, the common denominator is 6

2/3 becomes 4/6

1/2 becomes 3/6

Now subtract the fractions with the common denominator

4/6 - 3/6 = 1/6

The answer is 1/6

Hope this helps. Please mark me as Brainliest. Thanks!
