Why is the distributive property appropriate for two-digit multiplication?
Rina8888 [55]
Here's an example:

25\times93=(20+5)\times(90+3)
25\times93=20\times(90+3)+5\times(90+3)
25\times93=20\times90+20\times3+5\times90+5\times3
25\times93=1800+60+450+15
25\times93=2325

A triangular prism has a length of 5 inches, a base of 2 inches, a height of 2 inches, and sides of 2 inches and 3 inches. Find
riadik2000 [5.3K]
Volume of the Triangular prism = 1/2 (base*height*length) 
<span>V = 1/2 (2 * 2 * 5) </span>
<span>V = 10 cubic inches. </span>

<span>For the surface area, you can divide the prism into parts: </span>
<span>It's made of three rectangles and two equal triangles. </span>

<span>For the two triangles: </span>
<span>The area of each of the triangles is 1/2(base x height) </span>
<span>Area of each triangles = 1/2 (2 * 5) </span>
<span>Area of each triangles = 5 inches^2. </span>

<span>For the three rectangles: </span>
<span>* one is equal to base x length, </span>
<span>Rectangle1 = 2 x 5 </span>
<span>Rectangle1 = 10 inches^2. </span>

<span>* another is equal to side 1 x length </span>
<span>Rectangle2 = 3 x 5 </span>
<span>Rectangle2 = 15 inches^2 </span>

<span>* and the last is equal to side 2 x length. </span>
<span>Rectangle3 = 3 x 5 </span>
<span>Rectangle3 = 15 inches^2 </span>

<span>Adding all the components up, </span>
<span>10 + 15 + 15 + 5 + 5 = 50 inches^2 </span>

<span>Therefore, the surface area of the prism is greater than volume 50 > 10

How can N+4/3=1/3,What is the value of N
ivann1987 [24]
N + 4 / 3    = 1 / 3

Multiply both sides by 3 :

3* ( N + 4 / 3 ) = 3 * ( 1 / 3 )

∴

N + 4  = 1

Subtract  4 from both sides:

N + 4 - 4 = 1 - 4

N = - 3

hope this helps !.
