nevsk [136]

Answer:

There are four correct expressions.

Step-by-step explanation:

Four correct expressions:

{x}^{2}  - x - 42

{x}^{2} +6x −7x −42

x(x−7)+6(x−7)

2x +6x-7x−42

Simplify:

{x}^{2}  - x - 42

(x+6)(x−7)

x(x−7)+6(x−7)

2x +6x-7x−42

{x}^{2} −7x+6x−42

{x}^{2}  - x - 42

Cylinder A has radius r and height h as shown in the diagram. Cylinder B has radius 4r and height 4h. How many times greater is
svetlana [45]

Answer:

  • The surface area of Cylinder B is 16 times the surface area of Cylinder A

Step-by-step explanation:

<u>Note</u>: <em>It is assumed we are looking at  the total surface area (but the answer would be same for both cases)</em>

<h3>Given</h3>

  • Cylinders A with radius - r, height - h,
  • Cylinder B with radius - 4r, height -  4h.

<h3>To find </h3>

  • The ratio of total surface areas of cylinder B to A

<h3>Solution</h3>

Total surface area of cylinder A is:

  • S_A = 2\pi  r(h + r)

Total surface area of cylinder B is:

  • S_B = 2\pi(4r)(4r + 4h) = 8\pi(4)(r + h) = 32\pi(r + h)

Find the ratio of areas:

  • \cfrac{S_B}{S_A} =\cfrac{32\pi(r+h)}{2\pi(r+h)} =16
