Step-by-step explanation:
Answer:
x=58
FDE=61
Step-by-step explanation:
Since FDA and ADC are supplementary angles, their angle measures add up to 180 degrees. You can therefore write down the following equation:
2x+3+x+3=180
3x=174
x=58 degrees
FDE=ADC= x+3=61 degrees. Hope this helps!
Answer:
36.88
Step-by-step explanation:
6.1 + 6.3 = 12.4
3.2 x 12.4 = 39.68
39.68 - 2.8 = 36.88
Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.
