Trust me:  You must know how to do this basic factoring yourself.

x^2 -5x - 6 factors into (x-6)(x+1).  Note how I got that:  -6 is the product of 1 and -6, and -6 + 1 = -5.

You could also factor this by grouping:

x^2 -5x - 6 = x(x-6) + 1(x-6).  Note how the middle terms combine to produce -5x and how (x-6) is a factor common to both terms; this leaves (x+1).  So the factors are (x-6)(x+1).

Answer:

The sin A expressed in ratio form is \frac{\sqrt{6} }{4}

Step-by-step explanation:

From the given right angled triangle diagram, sin A is calculated as follows;

sin \ A = \frac{Opp}{hypo} \\\\sin \ A = \frac{2\sqrt{6} }{8} \\\\sin \ A = \frac{\sqrt{6} }{4}

Therefore, the sin A expressed in ratio form is \frac{\sqrt{6} }{4}

Explain how you can use base ten blocks to find 1.54+ 2.37
solong [7]
0.00

*First column to your left - ones column (1)
*Column just after decimal place, in the middle - tenths column (1/10)
*Column to the far right - hundredths column (1/100)

The only numbers that can go in these columns are 0-9.

-------------

1.54 + 2.37 

= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)

= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100

= 3 + 8/10 + 11/100

= 3 + 8/10 + (10/100 + 1/100)

= 3 + 8/10 + (1/10 + 1/100)

= 3 + 8/10 + 1/10 + 1/100

= 3 + 9/10 + 1/100

= 3.91
