Step-by-step explanation:
as we can see that the sides are in the ratio of 2:1 and are consecutive
so
a;b=2:1
a=4
b=8
P = 2(L + W)
P = 60
L = 2W - 3
60 = 2(2W - 3 + W)
60 = 2(3W - 3)
60 = 6W - 6
60 + 6 = 6W
66 = 6W
66/6 = W
11 = W <=== the width is 11 ft
L = 2W - 3
L = 2(11) - 3
L = 22 - 3
L = 19 <=== the length is 19 ft
The answer of the following subtraction is 5
Step-by-step explanation:
As per the question the equation will be

To find the subtraction,
The steps are as follow
=
=1-2 +
[ we took the variables with same power together]
=5
Hope it helps you.
If we are supposed to assume that QS=TV
4v+3=7v-9
minus 4v both sides
3=3v-9
add 9
12=3v
divide 3
4=v
v=4
sub back
4v+3=QS=TV
4(4)+3=QS=TV
16+3=QS
19=QS=TV
then answer is C
