Vol=area x Height
length= 3
breadth= X
Height = 2
area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so
42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7
so the missing length is 7cm
Answer:
The perimeter of the hexagon is equal to 36 units
Step-by-step explanation:
Let
x-------> the length side of the hexagon
L-----> the length of the rectangle
W-----> the width of the rectangle
we know that the perimeter of the hexagon is equal to the perimeter of the rectangle is equal to so
-------> equation A
-------> equation B
-------> equation C
Substitute equation B and equation C in equation A
Solve for L
Find the value of x
Find the perimeter of hexagon
Answer:
2/7
Step-by-step explanation:
red marbles(R)=3
white marbles (W)=4
total marbles =7
possibility of both white marbles =2/7
The answer would be $30.72 because 3.84 • 8 = $30.72
Then answer is A because of how PR and QR are similar
