Answer:
b^2 = 46
b = √46 (or 6.78 rounded)
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)
First I did what’s inside the parentheses, (6x2) and got 12.
Then I divided 16 by 22 and received 0.72.
I added 0.72 with 12 and the result was 12.72.
Last step was to subtract 12.72 - 8 and that equals 4.72
(d-2.8)/0.2=-14
d-2.8=-14*0.2
d-2.8=-2.8
d=-2.8+2.8
d=0
