So first you need to add 4 to each side to get (x+5)^2=16. Next you need to take the square root of each side to get √(x+5)^2=+-√16. After that simplify to get x+5=+-4. Now subtract 5from both sides to look like x=-5+-4. Now just do x=-5+4 and x=-5-4 then solve to get x=-1 and x=-9.
Answer: 2 / 15
Step-by-step explanation:
3 red / 10 total
4 white / 9 total
3/10 * 4/9 = 12/90 = 2/15
Answer:
y=2x+3
Step-by-step explanation:
a to C would be 4 3/4 + 2/3
3/4 + 2/3 = 9/12 + 8/12 = 17/12 = 1 5/12
1 5/12 + 4 = 5 5/12 total distance
Answer:
37.7
Step-by-step explanation:
EF and ED define the Tangent of D
Tan(37) = side opposite D / side adjacent to D
Opposite means a line (FE) that is not connected to the angle. It is never the longest line (hypotenuse) in a Right Triangle
Adjacent means the leg that is connected to the angle, but is not the hypotenuse.
Tan(D) = opposite over adjacent
Opposite = x
Adjacent = 50
Tan(37) = 0.7536 rounded to 4 places, but I've kept the exact value in my calculator.
0.7536 = x / 50 Multiply both sides by 50
0.7536*50 = x
x = 37.6777
The nearest 1/10 is 37.7
