This is the concept of algebra, given that the length of the rectangle is 5x-2 and the width is 3x+1, the perimeter is 2(5x-2)+2(3x+1). To get the total distance Zohar needs to cut with the scissors, we substitute the value of x=4 in the expression for perimeter. Hence we shall have:
2(5x-2)+2(3x+1)
=2(5*4-2)+2(3*4+1)
=2(20-2)+2(12+1)
=2(18)+2(13)
=36+26
=62 cm
The answer is 62 cm
The volume of the rectangular prism is found with 7x4x212=5936
The volume of the cube is found with 12x12x12, because all the sides on a cube are equal= 1728
To find how many cubes fir in the rectangular prism, you divide the volumes
5936 divided by 1728= 3.435 when rounded to the nearest thousanth
1.847 rounds to 1.85 because the number in the thousandths place bumps it up since it is greater then 4. 1.798 rounds to 1.8 because the number in the thousandths place bumps the nine up to ten and you can't have a two digit number where there is only supposed to be one. so that "ten" bumps the 7 up to 8.
I think it’s the bottom one
