So.... notice the picture below
now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm
so, k + k + b = 18
or 2k + b = 18
thus

so... one can say that

and you can simplify it if you wish.. not sure you have to
X= -14/13
Solve for X by simplifying both sides of the equation, the isolating the variable.
I hope this helps.
Answer:
2(w+6)
Step-by-step explanation:
Answer: 
has the least value because it's further from 0. The biggest negative number is the least because that number is further from 0. The smallest negative number is the biggest because it's closest to 0.
<u>Example:</u>
Find the least value of the following numbers: -6,-2,-1,-4,-10,-3
The least value in this problem is -10 due to the fact it's further from 0. The greatest value is -1 because it's closest to 0.
Least to Greatest Order: -10,-6,-4,-3,-2,-1
Greatest to Least Order: -1,-2,-3,-4,-6,-10
Answer:
the student may have made the mistake because the student was paying more attention to how many blocks he was filling in rather than how much he was filling in.
to solve the problem correctly you would just switch the decimals
0.8 > 0.08
0.8 should have 80 blocks filled
0.08 should have 8 blocks filled
