Let w=width and 4 + w=
kozerog [31]

Answer:

Part 1 : w^2+4w-60=0

Part 2 :

w=6

l = 10

Step-by-step explanation:

Part 1:

Let the width of the rectangle = w

Length of the rectangle = w + 4

Area of the rectangle is given as

60 Sq Yrds

60=w(w+4)

60=w^2+4w

w^2+4w-60=0

Hence this expression represents the area of the rectangle. Solving which for w will give us the width of the rectangle.

Part 2:

(w+10)(w-6)= 0

either (w+10) = 0

or

(w-6)=0

or both are zero

(w+10) = 0 ⇒ w = -10

not possible as the dimension can not be 0

(w-6)=0  ⇒ w=6

Hence the width is 6 yards

And thus the length will be 6+4 = 10 yards

You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher.  What is the  P ( A ∪ B ) ?
creativ13 [48]

set A = {2, 4, 6, 8, 10}   (only even cards)

set B = {8, 9, 10}    (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common. 

So the answer is: P(A ∩ B) = {8,10}

A girl buys a shirt that was originally $45 but is now $15. What is the rate of change?
jok3333 [9.3K]
So first we find the change
45 to 15=45-15=30

change is 30
rate of change=(change)/(original)

original=45
change=30
30/45=10/15=2/3=0.66666666=66%
rate of change is 66.66%
