Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
= 
Thus the ratio of Δ EFG to Δ LMN = 2 : 1 → C
Answer:
a) -10 b) 7
Step-by-step explanation:
a) 2(x+ 3) = x - 4
2x + 6 = x - 4
2x - x = -6 - 4
x = -10
b) 4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 14/2
x = 7
Answer:
b
Step-by-step explanation:
because we can not some times change the places in addition so b is the correct answer
3, assuming 2x2 is 2x squared, u will get
4 + 6x3 - 10x2
So 3 terms
