The sum of two numbers is 22 and their difference is 12 what are the numbers

nlexa [21]

Answer:

The numbers are 17 and 5

Step-by-step explanation:

x + y = 22

x - y = 12

Add y to both sides of the equation

x = 12 + y

Substitute new value for x into first equation

12 + y + y = 22

Add the y's

12 + 2y = 22

Subtract 12 from both sides

2y = 10

y = 5

22 - 5 = 17

The numbers are 17 and 5

Hope this helps :)

mr.lumen replaced a square window with a rectangular one.The new window is 3 ft wider and 2 ft higher than the square one.it has

stira [4]

Alright, lets get started.

Suppose the original square window has the side = x feet

The new window is 3 ft wider and 2 ft higher than the square one.

Means length of the new window will be = $(x+3)$

Width of the new window will be = $(x+2)$

So the area of the new window will be = $(x+3)(x+2)$

So the area of the new window will be = $x^2 + 2x + 3x + 6$

So the area of the new window will be = $x^2 + 5x + 6$

As given in question the area of 30 square feet for the new window, hence

$x^2 + 5x + 6 = 30$

$x^2 + 5x - 24 = 0$

Factoring

$(x+8)(x-3) = 0$

x = -8 or x = 3

Side could not be negative hence

side of the original square window will be = 3 feet : Answer

Hope it will help :)
