Answer: MN=2
Step-by-step explanation:
Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
I think the slope of L'M' is still 1.75 and it still passes through point C.
81
(-9)(-9) is 81
Multiplying two negatives gives a positive
