22 is the answer for 23x-1 for x=1
Answer:
Let the measure of each side of the square be " x " cm.
then ,
area of square = x²
After we folded the square into a rectangle ,
length of rectangle = x
breadth of rectangle = x/2
perimeter of rectangle = 36 cm

hence ,
side of square = 12 cm
therefore ,
area of square = 12 × 12 = 144 cm²

X=-4 you have to substitue first so you put the equation where the X is and then you would distribute and then add the numbers that have the common exponent
857 x 132= 113,124
