Answer:

Step-by-step explanation:

Now taking 3x to right hand side of the eqn . & +1 to the left side eqn. , sign of 3x changes to -3x & +1 changes to -1 .

Now solving this , we get the value of x.

I guess it’s A not sure tho
the original cost is "x", which is the 100% of the original price, and we also know that €336 is its price increased by 40%, namely 100% + 40% = 140%, so

Answer:
6 cm
Step-by-step explanation:
A = 1/2(b + 12)(4)
36 = 1/2(b + 12)(4)
72 = (b + 12)(4)
18 = b + 12
18 - 12 = b
6 = b
or
b = 6 cm
First put the equation in point slope form:
y - 4 = 2x - 6
y = 2x - 2
Then graph this, which will look like this
