Answer:
x+2 x+2 x+2
Step-by-step explanation:
i think it's 3/4 though i'm not entirely sure
90 - 50 = 40
40 / 8 = 5
x = 5
-2.183 • 10^2
Step by step
2.2•106 - 4.3•105
223.2-451.5
-218.3
(move decimal place 2 to the left - the 2 represents what the power of 10 should be and since the decimal moves to the left, that means that the 2 should be positive)
so your answer is -2.183 • 10^2
4,6,8,10,12
Hope this helps!
