(X+5)+(x-5)=56 what does x=?
kirill115 [55]

Answer:

x=28

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+5+x−5=56

x+5+x+−5=56

(x+x)+(5+−5)=56(Combine Like Terms)

2x=56

2x=56

Step 2: Divide both sides by 2.

2x/2=56/2

x=28

A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4 cm and an area of 12 cm2. What is the vol
Pavel [41]

Solution:

Let me define pyramid first.A pyramid is a Polyhedron , whose base  can be any polygon and it's faces are triangular which meet at a point called vertex.

Volume of Pyramid =  \frac{1}{2}\times{\text{Area of Base}\times{\text{Height}

Side of base which is an equilateral triangle= 4 cm

Area of whole pyramid = 12 square cm

Area of Equilateral triangle having side 4 cm=\frac{\sqrt3}{4}\times(Side)^2=\frac{\sqrt3}{4}\times(4)^2=4 \sqrt3 cm²

So, Area of three triangle which are faces of pyramid = (12 - 4 √3)cm²

Area of triangle = \frac{1}{2} \times (Base)\times(Height)

12 - 4 √3= \frac{1}{2} \times (4)\times(Height)

Height =\frac{12-4\sqrt3}{2}

Height=(6-2√3) cm

Volume of pyramid = Area of Equilateral triangle which is it's Base × Height of Pyramid

          =4√3 × (6-2√3) cm³

           =(24 √3 -24)

           = 24 (1.732-1)

          =24 × 0.732

          =17.568 cm³

A. 0.33 is a valid response, since it represents 33%.

B. 56% is also a valid response.

C. 7/8 is also a valid response since it represents 0,875 or 87,5%.
