Answer:
SAS postulate
Step-by-step explanation:
AD (common)
AC = BD (both are diameters)
Angle COD = Ange AOD (vertically opposite angles)
Angle CAD = Angle BAD (angle on the circumference is half the angle at the centre)
Therefore, ABD and DCA are congruent by SAS postulate
Answer:
-11
Step-by-step explanation:
-6-5
-(6+5)
Because accepting credit cards cost the business small transaction fees. These businesses already have a paper thin profit margin, meaning if you buy less than $10 and use credit card, their profit is little to non-existent.
A- positive
B-negative
C-positive
A was positive because 5-2 would be positive 3.
B was negative because 8-12 would be negative 4.
C was positive because -5+8 is positive 3.
For this case we have the following multiplication:
We can rewrite this operation to facilitate the calculation.
We have then:
From here, we apply the distributive property.
We have then:
Rewriting we have:
Finally adding all the numbers we have:
Answer:
The value of 6 * 298 is 1788 and the calculations can be provided as follows:
