Answer:
-4,5
Step-by-step explanation:
Step-by-step explanation:
A) opposite sides in a rectangle is always equal
B) 9x+12 = 4x +47
Transpose = 9x - 4x = 47 - 12
solve = 5x = 35
Divide both sides by 5
x = 7
Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
Answer:
Step-by-step explanation:
Use the formula for calculate the distance between two points:
Calculate the distance AB. Substitute the coordinates into the formula. Then:
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
