The perimeter of a rectangular garden is 100 feet​ (ft). the area of the rectangular garden area is 600 ft2. find the length and
svlad2 [7]
Let the length be x and the width be y:
Area=x*y=600
thus
x=600/y

Perimeter=2(L+W)
100=2(x+y)
substituting the value of x we obtain:
100=2(600/y+y)
solving for y we shall have:
50=600/y+y
50y=600+y^2
thus
y^2-50y+600=0
solving the quadratic we obtain:
y=20 or y=30
thus the length=30 ft and the width=20 ft

Which polynomial represents the difference below? 10x^8 + 11x^6 - 2x + 5 - (8x8 + 6x7 - 5)​
katrin2010 [14]

Answer:

2x^8-6x^7+11x^6-2x+10

Step-by-step explanation:

To find: 10x^8+11x^6-2x+5-(8x^8+6x^7-5)

Solution:

Like terms refer to terms with same variables and same powers.

Two like terms can be added or subtracted.

Consider the following expression:

10x^8+11x^6-2x+5-(8x^8+6x^7-5)=10x^8+11x^6-2x+5-8x^8-6x^7+5\\=(10-8)x^8-6x^7+11x^6-2x+(5+5)\\=2x^8-6x^7+11x^6-2x+10

(Here, like terms are added or subtracted)
