you multiply 35 to 72 to get 2520 and then multiply 23 to 94=2139 add both of the answers to get 4659
11/20 is already reduced you cannot simplify this fraction
Answer:
(2,5)
Step-by-step explanation:
The rule to 90 degrees about the origin is (x,y) to (-y,x). You basically switch the values of y and x but remember the value of y is negative. The value of y is -2 so -2 is now 2 since the rule changed the sign (-2×-y=2) and 5 isnt affected except it is the x value. Just know that since they r switched, x is now 2 and y is 5 when rotated 90 degrees about the origin.
To round it to the nearest unit it would be 38. To round it to the nearest ten it would be 40.
