I hope this helps :-)
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
<span>4x = −4
</span>
Question 2
<span> 2(2x − 5 − 4) = 160 − 17
4x-10-8 = 160-17
4x-18=143
4x = 161
x=40.25
</span>
Question 3
<span>4(2z + 3) = 12
8z +12 = 12
8z = 0
z = 0
</span><span>Question 4
</span>
<span>5(2x − 6) + 20 = 10
10x-30+20=10
10x-10=10
10x =20
x=2
</span>
<span>Question 5
</span>
<span>5x + 10 = 5x − 8
5x+18=5x
18=0
Zero solutions
