Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
Answer:
a. Enlargement
b. Reduction
c. No Change
d. Enlargement
e. Reduction
f. Reduction
g. Reduction
Step-by-step explanation:
X equals 13/3 and Y equals 1/13 sorry if I am wrong
If the space is time, so the answer is 21x and -30x
