Answer:
The height of the cylinder is 4x units
Step-by-step explanation:
see the attached document
Draw a right rectangular prism. Draw it so one face is pretty much the way you would see it if it was real. The other two faces you can see have a slant to them.
Label the face you can see as x and y. Name any of the slanted lines as z. Put cm for centimeters behind the letters.
Volume = x*y*z the units here are cm^3
Why because you are multiplying cm*cm*cm together.
The surface area is a whole different ball game.
you have 2 surfaces who have areas of x*y There's one in front of you and one you cannot see
You have a top and a bottom that is y*z each that's 2y*z
You have two surfaces that are x*z each and that's 2x*z
The total surface area = 2xy + 2xz + 2yz
The units here are cm*cm or cm^2
Answer:
3
Step-by-step explanation:
The rule for secants tells you
EC·ED = EB·EA
(x+4)(x+5) = (x+1)(x+12)
9x+20 = 13x+12 . . . . . . simplify, subtract x²
8 = 4x . . . . . . . . . . . . . . add -12-9x
2 = x
The value of x is 2.
When it comes to fractions yes you do. But to make it easier just multiply the denominators and that should give u a common denominator, they don't always have to be least common.
