4 place holder zero will be needed
Answer:
We would need to add 90+10 first instead of 10+4.8.
Step-by-step explanation:
When evaluating expressions, we follow the order of operations:
P (parentheses); E (exponents); M/D (multiplication/division from left to right); and A/S (addition/subtraction from left to right). The first thing we look for is parentheses.
When we use the associative property as Morgan did to rearrange the problem, this changes the order we begin in. It does not, however, change the answer.
Answer:
a=1.5, b= 3
Step-by-step explanation:
sum of all sides will give us perimeter. Therefore
2a+b+6a+2b+1+4a=28
12a+3b+1=28
12a+3b=27....eqn1
since t two sides of this isosceles triangle are equal:
2a+b=4a
2a=b
substituting 
in the first equation whenever we encounter a we will have:
6b+3b=27
9b=27
b=3
therefore
