Point A' is at (-2,-2)
Point D' is at (-2,4)
Just multiply each coordinate by 2
Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9.
.

Step-by-step explanation:
From the general properties or laws of logarithm, we have the

where both log are now express in the natural logarithm base.
i.e 
hence we can express our
.
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence
.

1 / 10 is the easiest answer. Remember ratios are just percentages. It could also be 2/20, 3/30, as long as it is 10%.
That square in a means that it’s 90 degrees and b is 70. Well it says that ab = bc. And ab together is 90+70 which is 160. A straight line is 180 in total so to figure that other side of b out do 180-70 which is 110. So now you have 110, and to match ab you need 50 more degrees for bc. Therefore c is 50 degrees
