both √25 and -√16 are rational
He jogged 3/4 (.75) a mile for every mile she jogged
Answer:
5
Step-by-step explanation:
This is Pythagorean triple 3-4-5 or you can verify by plugging into Pythagorean Theorem:

c = 5
Answer:
60
Step-by-step explanation:
Length=4w
Width=w
Area=length×width
144= 4w × w
4w²=144( Divide both sides by 4)
w²=36
w²-36=0 (Factorise the Quadratic Equation)
(w+6)(w-6)=0
(w+6)=0 or (w-6)=0
w= -6 or w=6
Since length can't be a negative value,
w=6
4w=6×4=24
Perimeter= 6+6+24+24=60
Answer:

Step-by-step explanation:
We are given the equations

We need to combine like terms. As there are no exponents or numbers outside the parenthesis, we can just drop them and add all like terms
