25x² - 9

Step-by-step explanation:

if you multiply both of the dimensions, you'll use sum and difference of two squares. first, square the first term which equals to 25x². next, copy the negative sign. then, square the last term which equals to 9.

35 circles

Step-by-step explanation:

Diameter of circle   = 2r  =   2* 5  = 10

number of circles that can be cut length wise  =   70/10   = 7

number of circles that can be cut width wise    =  60/10   =   6

since the first row is common

total number of circles that can be cut   =   7*5 =  35 circles

42

Step-by-step explanation:

Find the diameter :

Diameter = 5 x 2 = 10 cm

Find the number of circles that can fit length-wise:

Number of circles = 70 ÷ 10 = 7

Find the number of circles that can fit breadth-wise:

Number of circles = 60 ÷ 10 = 6

Find the number of circles that can fit in the rectangle:

Number of circles = 7 x 6 = 42

42 circles can be cut out from that rectangle.
