Answer:
and 
Step-by-step explanation:
(a)
A = 
× 4
× 
= 2 ×
= 
× 
← rationalise the denominator
= units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4 )² + ( )²
= 32 + 
= 
+
= 
( take the square root of both sides )
h = 
= 
× ← rationalise the denominator
h =

Answer:
the first one is negative
Step-by-step explanation:
1= -168
2= 360
3= 0
4= 360
a negative times a negative is a positive, 1 has 3 negatives tho so its gonna be a negative. 3 would be the other one but it has a zero making the answer 0
Here, 635/9
Nearest divisible of 9 is 630 so,
It would be: 70 * 9 + 5
In short, Your Quotient would be 70
Hope this helps!
I am sorry but this cannot be put as a mixed number. The answer is 11. To dot his do 11/3 divided by 2/6 u would first do same change flip and do 11/3 times 6/2 which then u would multiply straight across and u would get 66/6 which equals 11 because 66 divided by 6 equals 11. I hope this helped u! ;)
