Complete the factored form of the algebraic expression 18a + 3 = 3( _+_)

1 answer:

4 0

So to factorise an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like:
3(6a + 1)

What is the length of stack A G with bar on top in the rectangular prism? Round your answer to the nearest tenth.

Leviafan [203]

I saw the image that should accompany this problem.
It is a rectangular prism and the base has a right triangle with a measure of the following: long leg = 18cm ; short leg = 16cm

We need to look for the hypotenuse because it serves as the long leg of the right triangle where AG is the hypotenuse.

base triangle
a² + b² = c²
(16cm)² + (18cm)² = c²
256cm² + 324cm² = c²
580 cm² = c²
√580cm² = √c²
24 cm = c

2nd triangle: long leg = 24cm ; short leg = 16cm
(24cm)² + (16cm)² = c²
576 cm² + 256 cm² = c²
832 cm² = c²
√832 cm² = √c²
28.8 cm = c

the length of stack AG is 28.8 cm.

Show in form of p/q 0.235 0.5777.

almond37 [142]

Answer:

Step-by-step explanation:

Given the decimal numbers 0.235 and 0.5777, to show in the form p/q means we are to express the decimals in fraction in its lowest form. This is as shown below;

0.235 = 235/1000

= 5*47/5*200

= 47/200

0.235 = 47/100 where p = 47 and q = 200

For 0.5777

0.5777 = 5777/10000

This fraction can not be expressed further into its lowest term therefore p = 5777 and q = 10000
