Answer:
the correct answer is d) i.e the above statement has a solution which is neither positive nor negative
because X+10=10
or,X=10-10
X=0
and 0 is neither positive nor negative
Answer:
communicative, you can remember this by saying (the rule for the communicative property, is as easy as can be, just remember a+b is the same as b+a )

Step-by-step explanation:
Answer: It would take 7 hours.
Step-by-step explanation:
715/11 = 65
65 miles per hour
455/65 = 7
<span>Let the extension of the length and width be x.
The new dimensions are: Length = 8+x
Width =3+x
Area = 104 ft squared
Area of a rectangle = Length x Width
Therefore,
(8+x)(3+x) = 104
x^2 +11x +24=104
x^2 +11x +24-104=0
x^2 +11x-80=0
Factorize using splitting the middle term method.
X^2 +16x-5x-80=0
x(x+16)-5(x+16)=0
(x-5)(x+16)=0
either x-5 = 0 or x+16=0
x=5 or x=-16
length and width measure cannot be negative.
Therefore, the extension of the length and width is 5 feet each.</span>
