5(x-3)+2x+21=3(x+4)+2x

Mathematics
1 answer:
nekit [7.7K]2 years ago
3 0

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−3)+2x+21=3(x+4)+2x

(5)(x)+(5)(−3)+2x+21=(3)(x)+(3)(4)+2x(Distribute)

5x+−15+2x+21=3x+12+2x

(5x+2x)+(−15+21)=(3x+2x)+(12)(Combine Like Terms)

7x+6=5x+12

7x+6=5x+12

Step 2: Subtract 5x from both sides.

7x+6−5x=5x+12−5x

2x+6=12

Step 3: Subtract 6 from both sides.

2x+6−6=12−6

2x=6

Step 4: Divide both sides by 2.

Hope this helps!

SA = 2tr2 + 2trh
julsineya [31]

Given:

Radius of the cylinder = 5 in

Height of the cylinder = 30 in.

To find:

The surface area of the cylinder.

Solution:

The surface area of the cylinder is:

SA=2\pi r^2+2\pi rh

Where, r is the radius and h is the height of the cylinder.

Putting r=5,h=30,\pi=3.14 in the above formula, we get

SA=2(3.14)(5)^2+2(3.14)(5)(30)

SA=2(3.14)(25)+942

SA=157+942

SA=1099


Therefore, the surface area of the cylinder is 1099  square inches.
