2x+x-7+3x-20=87cm
6x-27=87
6x=114
x=19
Therefore the sides are:12cm, 38cm, and 37cm
I know there must be an equation to do this, but there is a simpler way.
Just factor number 72 into two numbers which, when multiplied, equal 72. Two of such numbers are 9 and 8, and you can see that the difference between those two numbers is just 1. So that is the answer to your question - the length of the patio is 9 feet, whereas the width is 8 feet.
Ten thousand is the place value of the 9 in that number
A circle obviously. A perpendicular bisector requires right angles which a circle can physically never have.
Answer:
5*10^10.
Step-by-step explanation:
9 - 4 = 5.
The last part of the 2 numbers is 10^10,
so the answer is 5* 10^10.
