Let length be x feet
length= x
width=x-4
area = 32
length * width=32
x(x-4)=32
x^2 - 4 x -32=0
(x-8)(x+4)=0
x=8 feet
length=8 feet
width=4 feet
perimeter=2(len+wid)
=2(8+4)
2*12=24 feet
Neagtive means go backwards or oposite
it takes away that many units
Answer:
I would say 25 :)
Step-by-step explanation:
Area = length x width. All of the sides are the same and our given length is 5. 5 x 5 = 25! Hopefully this helps.
Answer:
(-2,-1) WHen rotating it 180 counterclockwise it will be (-x,-y)
Answer:
Age of younger brother is 14 years..
And age if elder brother is 29 years.
Step-by-step explanation:
Let us denote 'x' as the age of smaller brother,
then, the age of younger brother will be x+15 years.
Equation formed:-
x+x+15 =43
2x+15 = 43
2x = 43-15
2x = 28
X = 28/2
X = 14
Age of younger brother is 14 years.
Age of elder brother = x + 15
Age of elder brother 14 + 15 = 29 years.
