Answer:x=+3/7 or x=-3/7
Step-by-step explanation:
49x^2=9
Divide both sides by 49
49x^2 ➗ 49=9 ➗ 49
x^2=9/49
Taking the square root of both sides we get
x=±√(9/49)
x=±(3/7)
x=+3/7 or x=-3/7
Detailed Answer:
Diameter = Radius * 2
Radius = Diameter/2
a) 64cm
r = 32 cm
Diameter = 32 * 2 = 64cm
b) 25.2 m
r = 12.6 m
Diameter = 12.6 * 2 = 25.2 m
c) 29.5 in
r = 14 3/4 = 14.75
Diameter = 14.75 * 2 = 29.5 in
d) 64 cm
r = √32 cm^2 = 32 cm
Diameter = 32 * 2 = 64 cm
e) 49.32 ft
r = 24.66 ft
Diameter = 24.66 * 2 = 49.32 ft

Answer:
Non linear( it doesn't go through the 0
Step-by-step explanation:
3s + 135 = 4.5s + 45
Now move the variables and coefficients
135 = 1.5s + 45
And then the numbers
90 = 1.5s
Simplify
90/1.5 = 1.5s/1.5
60 = s
Hope this helps!
