Answer:
The common differences is 5
Step-by-step explanation:
The difference is 5. Why? Because 5 is added to each term to arrive at the next term. so ... the difference a2 - a1 = 5.
E.g. -31 + 5 = -26
The triangle tells us that 8x - 4 is equal to 4x + 16 we set them equal to eachother 8x - 4 = 4x + 16 and solve for x
8x - 4x - 4 = 16
4x + 4 - 4 = 16 + 4
4x = 20
x = 5
Then you plug the x value in for x on all 3 of the problems.
8(5) - 4 = 36
4(5) + 16 = 36
5(5) + 7 = 32
Therefore, the correct answer should be B
A. (140x110)+[(50x70)/2] = 15,400+1750= 17,150cm^2
b. (4x6)/2= 12cm^2
