Answer: (12,-3)\ \text{or}\ (3,-12)

Step-by-step explanation:

Given

The product of integers is -36

The difference of integers is 15

Suppose the integers are x and y

\Rightarrow x-y=15\\\Rightarrow x=15+y\\\Rightarrow xy=-36

Put the value of x in the product

\Rightarrow (15+y)y=-36\\\Rightarrow 15y+y^2+36=0\\\Rightarrow y^2+12y+3y+36=0\\\Rightarrow y(y+12)+3(y+12)=0\\\Rightarrow (y+12)(y+3)=0\\\Rightarrow y=-3\ \text{or}\ -12

\therefore x=12\ \text{or}\ 3

Pairs of integers are (12,-3)\ \text{or}\ (3,-12)

The length of a rectangle is "a" inches and the width is 3 inches more than its length. find the perimeter and the area
Alex73 [517]

Answer:

Step-by-step explanation:

Givens

Length = a

Width = a + 3

Formulas

P = 2L + 2w

Area = L * w

Solution

Perimeter

P = 2L +  2w

P = 2*a + 2(a + 3)             Remove the Brackets

p = 2a + 2a + 6                Combine

<u><em>P = 4a + 6</em></u>

Area

Area = L * w

Area = a (a + 3)

<u><em>Area = a^2 + 3a</em></u>
