Answer:
Step-by-step explanation:
D=106
E=54
F=20
D is an AEA im pretty sure meaning itʻll be equal to 106
E Is a vertical angle to 54
and for F everything will equal to 180 so 180-106-54=20
I hope this helps have a good day!
This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
Answer:
x = 5
Step-by-step explanation:
20(20-x)=300
1. Divide both sides by 20.
20(20-x)/20 = 300/20
2. Simplify.
20-x=15
3. Subtract 20 from both sides.
20-x-29=15-20
4. Simplify.
-x=-5
5. Divide both sides by -1.
-x/-1 = -5/-1
6. Simplify.
x=5
x={1+i√19 , 1-i√19}
solve this by using quadratic formula
