The way i do it, is sort of like this :

Is 7 a factor of 42? 
  Is 5 a factor of 42? 

7 is a factor of 42. 
It must be in multiples of 7!

Therefore, we have 5 on the other side, which makes it 5 x 7 = 35

What is the volume??????
Ugo [173]

Answer:

36\:\mathrm{in^3}

Step-by-step explanation:

The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:

A=\frac{1}{2}\cdot 3\cdot 4=6\:\mathrm{in^2}

The height is marked as 6 inches. Thus, the volume of the prism is:

\frac{1}{2}\cdot 3\cdot 4\cdot 6=\boxed{36\:\mathrm{in^3}}

the length of a rectangle is twice its width the perimeter is 48 cm what are the dimensions of the rectangle
inysia [295]

Answer:

The length=16cm and the width=8cm.

Step-by-step explanation:

Given that the length is twice the breadth or width of the rectangle

Let's assume that the breadth of the rectangle is x.

Thus the length is 2x.

Given perimeter=48cm

The formula for the perimeter of a rectangle is 2(l+b) where l is length and b is breadth.

2(x+2x)=48

(3x)=48/2

3x=24

x=8cm

2x=16cm
