Answer:
-25 and 2
Step-by-step explanation:
x + y = -23
xy = 50, so y = 50 /x
.
x + 50/x =-23, x^2 +23x - 50 = (x-2)(x+25)
so 2 and -25
Answer:
oceans and the Sun
Step-by-step explanation:
The Sun heats ocean water causing some to evaporate. Tides move the ocean water. Waves move ocean water onto the shore.
Let's assume
rent of the one chair = x
rent of the one table = y
3x + 2y = 24
8x + 4y = 53
multiply the first equation by 2
6x + 4y = 48
8x + 4y = 53
if we subtract from last equation to previous equation,
2x = 5
x = 2.5
y = 8.25
Therefore the cost of one chair is 2.5 dollars
the cost of one table is 8.25 dollars
Answer:
Step-by-step explanation:
Draw a triangle and label the sides (picture below):
● the length is 2x+2
● and the width or the height is 6x
The perimeter of a rectangle is the sum of the sides
● P = 2x+2 + 6x + 2x+2 + 6x
Isolate the similar terms
● P = (2x+2x+6x+6x) + (2+2)
● P = 16x + 4
