Which expression can be used to model the phrase “ the sum of three and a number”?
olga nikolaevna [1]

Answer:

x + 3

Step-by-step explanation:

A 'sum' means addition, 'a number' is represented by a variable, in this case, I chose 'x'.  I could have picked any variable I wanted.

The sum of three and a number means:  three plus some number, which is

 3 + x       in math language.     We write variables before constants, so it gets

                  rewritten as x + 3

A right prism has a base that is an equilateral triangle. The height of the prism is equal to the height of the base. If the vol
Romashka [77]

<u>Answer:</u>

Lengths of the sides (there are 3 sides in an equilateral triangle) of the base of prism is <u>5.72cm </u>each.

<u>Step-by-step explanation:</u>

As the base of triangular prism is equilateral:

∴ Area of base = (√ 3 / 4)× (side)²

According to question:

height of prism = height (side) of base

Volume of prism = 81 cm³,

∴ Volume of prism = Area of base x height

⇒  81 cm³ = (√ 3 / 4)× (side)² × height       ∵ side = height

⇒   81 cm³ = (√ 3 / 4)× (side)³

⇒  81 × (4/√3) cm³ = side³    

⇒  ∛(81 × (4/√3) cm = side

⇒  side = <u>5.72cm</u>
