Answer:
Option A
Step-by-step explanation:
Let,
Length = 5x
Breadth = 4x
Perimeter = 2(l + b)
=> 144 = 2(5x + 4x)
=> 144 = 2(9x)
=> 144 = 18x
=> 144/18 = x
=> 8 = x
Therefore,
Length = 5x = 5(8) = 40 cm
Answer:
45 boxes.
Step-by-step explanation:
30 / 2/3
= 30 * 3/2
= 90/2= 45

Answer:
10000
Step-by-step explanation:
Well substitute it
(5*2)^4
now follow order of operations (Parenthesis, exponents, multipication-division left to right, etc.)
5*2=10
10^4=10000
so the answer would be
10000 if y is 2
Answer:
Slope= -9
Step-by-step explanation:
To find the slope, you need to find two points on the line, so it would be (-1,4) and (0,-5)
You can use the formula and substitute the coordinates
Y2-Y1/X2-X1
so...
-5-4/0-(-1)
-9/1=-9
or you can find the distance between both points and simplify if needed.
So you move 9 down, and one to the right
