If n=2 (n-m)
given n=16 n= -4
require to find 'm'

q- find 'm'

answer !

4

Step-by-step explanation:

N=2 (n-m)

Substitute N=16 n= -4

16= 2(-4-m)

8 = -4 - m

m = -4+8

m = 4

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
