Answer:
The two expressions A and B are equivalent because the value of both expressions is same.
Step-by-step explanation:
Given: Expression A is 5(4+9) and expression B is 29+36.
To find: The reason why expressions A and B are equivalent.
First we solve expression A.
(using )
⇒
⇒
Now we solve expression B.
Clearly, the value of both the expressions is same.
Hence, the expression A is equivalent to expression B.
Answer:
as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition
such as
corresponding angles, AB//CD ,
alternate angles, AB//CD ,
interior angles, AB//CD
In my figure, a+b is always equal to 180degree if the X line is straight
a+b=180
imagine there is Y line which is parallel to the X line
c+d=180
a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)
then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
It's 216 because you would just do the equation from left to right since pemdas doesn't really effect the order here
Answer:
2000
Step-by-step explanation:
Hello,
A or C means 2 ways
and then a digit means 10 ways 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
so in total we have 2*10*10*10 = 2000 possible codes
Hope this helps
