N = 4.
I’m not sure if that was what you were asking though.
This is a very hard questions but i tried my best and i tried and even tried decimals! but it was too hard for me! sorry!
4x - 7 = 5
4x = 5 + 7
4x = 12 (divide both sides by 4 to get x)
4x/4 = 12/4
x < 3
Answer:
Step-by-step explanation:
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
Exact Form:x=6±√17
Decimal Form:x=10.12310562…,1.87689437…
I will do 9 only. You can do 11.
Question 9
sin(60) = x/8
sin(60)(8) = x
4•sqrt{3} = x
x^2 + y^2 = 8^2
(4•sqrt{3})^2 + y^2 = 64
16(3) + y^2 = 64
48 + y^2 = 64
y^2 = 64 - 48
y^2 = 16
sqrt{y^2} = sqrt{16}
y = 4
Do 11 the same way.
