Answer:
Step-by-step explanation:
Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2
we have answers as
8. u=16 and v = 
9) y=5 and x=
10) tan 30 =
So y=
x=
11) a=22 and b=11
12) b=1.5 and a=
13) y=
and x=10
It would just be 8 since an integer just means whole number.
Answer:
P = 16x+26y units
Step-by-step explanation:
Let the length is (x+8y) units
Width = (8x-x+5y) units
We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.
P = 2[(x+8y) + (8x-x+5y)]
= 2[(8x+8y+5y)]
= 2[8x+13y]
= 16x+26y
Hence, the required perimeter is 16x+26y.
Answer:
30 X 40 is 1,200
Step-by-step explanation:
I used a calculator lol
Athe answer is -2 because it is behind the 0 and will be negative and it is two lines away from the 0 so the answer is -2
