Answer:
x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3
Step-by-step explanation:
Solve for x over the real numbers:
(9 x - 4)^2 = 18
Take the square root of both sides:
9 x - 4 = 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)
Add 4 to both sides:
9 x = 4 + 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)
Divide both sides by 9:
x = 4/9 + sqrt(2)/3 or 9 x - 4 = -3 sqrt(2)
Add 4 to both sides:
x = 4/9 + sqrt(2)/3 or 9 x = 4 - 3 sqrt(2)
Divide both sides by 9:
Answer: x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3
Answer:
x = 0 , 1
Step-by-step explanation:
x² = x
x² - x = 0
x ( x-1 ) = 0
x=0 and x=1
Question 1= would equal 63 but why is there no 63?(did you type the answers right? or the angles right?
47+70=117
180-117=63
question 2 would be 36
54+90=144
180-144=36
Answer:
x>34
Step-by-step explanation:
w = x-8
w+x>60
x-8+x>60 (substitute x-8 for w)
2x-8>60
2x>68 (add 8 to both sides)
x>34 (divide both sides by 2)

A = πr² + πrl
306.00 = 3.14(6)² + 3.14(6)(l)
306.00 = 3.14(36) + 3.14(6l)
306.00 = 113.04 + 18.84l
- 113.04 - 113.04
192.96 = 18.84l
18.84 18.84
10.24 ≈ l
