BE = 6cm
BD = 12 cm
For a square, the diagonal are equal
so :::
AC = BD = 12 cm
Done :)
Answer:
Step-by-step explanation:
Question 1
BC - AC and AB will provide different answers when compared to AC + CB and CA + BC. This is because AC means A multiplied by C (AC) or C multiplied by A (CA); thus means AC and CA are the same. Also, CB means C multiplied by B (CB) or B multiplied by C (BC); thus means CB and BC are the same.
Hence, Finding AC + CB will provide the same answer as finding CA + BC
However, finding BC - AC will provide different answer to finding AB because BC - AC means the multiplication of A and C is subtracted from the multiplication of B and C - the answer thereof will most likely be different from the multiplication of just A and B.
Question 2
From the explanation above,
The "different" answer is
Find BC - AC and Find AB
The "same" answer is
Find AC + CB and Find CA + BC
Answer:
5760
Step-by-step explanation:
(2 * 10)^6 * 0.00009
First solve inside the parentheses
20^6 * 0.00009
Then solve powers
64'000'000 * 0.00009
Solve multiplications
5760
This answer might not be the one that is asked for, as the writing is kind of vague, but if you turn this inn with explanation you will not get it wrong
Red bricks : Grey bricks
5 : 2
Total parts = 5 + 2 = 7
7 parts = 224
-----------------------
Find 1 part:
-----------------------
1 part = 234 ÷ 7
1 part = 32
-----------------------
Find 5 parts:
-----------------------
5 parts = 32 x 5
5 parts = 160
----------------------------------------------
Answer: 160 Red bricks
