Arectangle or box has a perimeter of 76 inches. if two of the boxes are placed next to each other on the long side the new box is a rectangle shape but the perimeter of 112 inches .
what are the dimensions of the original rectangle ?

The dimension of the rectangle

Length =  20 inches

Breadth = 18 inches

Step-by-step explanation:

Given:

The perimeter of rectangle  =   76 inches

Perimeter of the newly formed rectangle = 112 inches

To Find:

Dimensions of the original rectangle = ?

Solution:

The perimeter rectangle

=> 2(L+B) =76 inches -----------------------(1)

If two of the boxes are placed next to each other on the long side the new box is a rectangle shape is formed

Then the perimeter of the new rectangle box  will  be

=> 2(L+B) + 2(L+B) - 2L =  112--------------------(2)

Substituting (1) in(2)

=> 76+ 76 - 2L =  112

=>156 -2L =112

=>2L = 156 -112

=> 2L = 40

=> L=

=>L = 20

Substituting L =20 in eq(1)

=> 2(20+B) =76

=> (40 +2B) = 76

=>2B = 76-40

=> 2B =36

=> B =

=> B = 18

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
