Answer:
b) Find the measurements of a rectangk with a perimeter of
26cm and an area of 1600cm
There is no way to get an area of 1600 cm using a perimeter as small as 26 cm.
Step-by-step explanation:
perimeter = 2(L + W) = 26, then L + W = 13, so L = 13 - W
area = L x W = 1600
substitute for L:
(13 - W)W = 1600
13W - W² = 1600
-W² + 13W = 1600
-W² + 13W - 1600 = 0
W² - 13W + 1600 = 0

Multiply the first bracket by 6.
Multiply the second bracket by 8
6(x+1)-5x= 8+2(x-1)
6(x)+6(1)-5x= 8+2(x)+2(-1)
6x+6-5x= 8+2x-2
6x-5x+6= 8-2+2x
x+6= 6+2x
Move +2x to the other side. Sign changes from +2x to -2x.
x-2x+6= 6+2x-2x
-x+6= 6
Move +6 to the other side. Sign changes from +6 to -6.
-x+6-6= 6-6
-x=0
Multiply by -1 for -x and 0
-x(-1)= 0(-1)
x= 0
Answer: x= 0
