Answer:
Properties of operations help a lot in solving problems related to integers and rational numbers.
<u>Step-by-step explanation:</u>
There are four properties of operations in math. These properties are applicable in case of addition and multipication but not in case of division and subtraction.
These properties are used to solve problems involving rational numbers as well as integers.These properties are associative,commutative, distributive and identity.
commutative property is A+B=B+A
⇒5+4=4+5
and A*B=B*A
⇒5*4=4*5
associative property ( 32+14)+7= 32+(14+7)
( 8*9)*7= 8*(9*7)
Identity property is 35+0= 35
1*58=58
distributive property is 15*21
⇒ 15*(20+1)
⇒15*20+15*1
15*21
⇒ 15*(22-1)
⇒15*22-15*1
Hello,
if we use Heron's formula:
p=(7.2+5.9+11.2)/2=12.15
Area=√(p*(p-a)(p-b)(p-c))
=√(12.15*(12.15-7.2)(12.15-5.9)(12.15-11.2))
=√357,09609375
=18,896986366878714557972599553433≈18.90
So i suppose Answer=D (with an error of 0.01)
Answer:
It is a factor.
Step-by-step explanation:
its definitely a factor
rule: put (x-2)=0
so x = 2
now put this 2 in the equation as x
which equals to 0, as a result its a factor
you can check the sum in the calculator by yourself
hope it helps.
