Answer:
Length = 2x+y cm and since it's a rectangle,
2x+y=3x-y ---------------- (i)
width = 2x-3 cm
It's perimeter,
2(2x+y+2x-3)=120 ---------------- (ii)
Solving both equations,
x = 14 cm
y = 7 cm
so length is, 2×14+7 = 35 cm
and width is, 2×14-3 = 25 cm
so area will be, 35×25 = 875 cm²

Answer:
The correct option is C) 210.
Step-by-step explanation:
Consider the provided information.
The analyst has narrowed down the list of potential stocks to 7. She choose and rank her top 3 picks.
Since the order matter so we will use permutation.
The formula for permutation is:
Substitute n=7 and r=3 in above formula.
Hence, the correct option is C) 210.
First I don’t know if it is a typo or what so im assuming
that you are just repeating the numbers. So 12 in represents 45 mile in the map
so 1 mile can be calculated by using ratio.
<span>Map distance = 1 mile ( 12 in / 45 mile) = 0.27 inch in the
map</span>
<span>my answer is not in your choices, i think, i didnt get your given. so just follow the steps and you will get the correct answer</span>
(x+40):12=88-78
(x+40):12=10
x+40=10*12
x+40=120
x=120-40
x=80
