Triangle 1:
a=1/2(175)(280)
a=24,500km^2

Triangle 2:
a=1/2(790)(480)
a=189,600km^2

189,600km^2 + 24,500km^2 = 214,100km^2

Hope this helps!

What is the value of X?
podryga [215]
Hey there! :D

36/6= 6

From this scale, we know that x has to be 42/6. Since the bigger triangle has a scale of 6 with the similar smaller triangle. 

42/6=7

So, x=7

I hope this helps!

What is the first step in solving In(x - 1) = In6 - Inx for x?
kobusy [5.1K]

Answer:

x=3

Step-by-step explanation:

In(x-1) = In(6) - In(x)

In(x-1) + In(x) = In(6)

In((x-1)x) = In(6)

In(x^2-x) = In(6)

x^2-x=6

x^2-x-6=0

x^2+2x-3x-6=0

x(x+2)-3(x+2)=0

(x-3)(x+2)=0

x=3 because x=-2 need to be cancel out
