1) Solve for radius
Radius = r
2) Solve for height
Height = h
3) in calculator enter : ( 2 x 3.14 x radius squared ) + ( 2 x 3.13 x radius x height )
8.7 you need to do the Pythagorean theorem
You were given one side length and the hypotenuse so your equation should b 18^2+x^2=20^2
Take the first 2 and take out -7x2. bringing it to (-7x2)(x-3)+(3x-9)
then take out 3 on the right side.
-7x^2 (x-3)+3 (x-3)
factors to (3-7x2)(x-3)
Answer:
Infinitely many
Step-by-step explanation:
12x+1=3(4x+1)-2
12x+1=12x+1
