Add: <br> 3x+9+8x + 12<br> 2x + 6+x² + 6x + 9
Oxana [17]

I'll treat these like they're two seperate problems because  how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)

First one: 3x+9+8x + 12

Collect like terms and simplify

(3x+8x)+(9+12)

11x+21

Second one: 2x + 6+x² + 6x + 9

Collect like terms and simplify

(2x+6x)+(6+9)+x^{2}

8x+15+x^{2}

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

A conical-shaped umbrella has a radius of 0.4 m and a height of 0.45 m. Calculate the amount of fabric needed to manufacture thi
bonufazy [111]

Answer:

The correct answer will be "0.756596 m²".

Step-by-step explanation:

The given values are:

The radius of an umbrella,

r = 0.4 m

The height of an umbrella,

h = 0.45 m

As we know,

The lateral surface of an umbrella will be:

⇒  \pi r\sqrt{r^2+h^2}

On substituting the values, we get

⇒  \pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}

⇒  0.756596 \ m^2

So that the amount of fabric needed will be "0.756596 m²".
