Step-by-step explanation:

Upper and lower surfaces of the cylinder:

\pi r^{2} =9\pi \\S=2*9\pi =18\pi

Side area of the cylinder:

S=sh=\pi dh=6\pi *3*8=144\pi

The total area:

S=114\pi +18\pi =162\pi =162*3.14=508.68

1.2x  = 36
x       = 30
1/5x = 6
So our final answer is 6 and 30.

Basing your answer on the appearance of the figures below, identify whether the mathematical expression is true or false.
KatRina [158]

Answer:

The mathematical expression is false

Step-by-step explanation:

* Lets use the figure to answer the question

- There are four triangles in the figure

- Δ ROB and Δ PTA appear congruent because:

# The side RO appears equal the side PT

∴ RO ≅ PT

# The side OB appears equal the side TA

∴ OB ≅ TA

# The side RB appears equal the side PA

∴ RB ≅ PA ⇒ SSS

∴ Δ ROB ≅ Δ PTA

- Δ DEF and Δ YXW appear congruent because:

# The side DE appears equal the side YX

∴ DE ≅ YX

# The side EF appears equal the side XW

∴ EF ≅ XW

# The side DF appears equal the side YW

∴ DF ≅ YW

∴ Δ DEF ≅ Δ YXW ⇒ SSS

- Δ ROB and Δ DEF have different shapes and sizes

∵ Δ ROB not appear congruent to Δ DEF

∴ Δ ROB ≠ Δ DEF

∴ The mathematical expression is false

Can someone please help?!!!
Nuetrik [128]

The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.

Plug in values of l and w in:

P=2(x+8)+2(x-1)

P=2x+16+2x-2

P=4x+14

So the perimeter of the rectangle is 4x+14 units

Hope this helped!
