Answer:
<em>1.1n</em>
<em>0.6p</em>
<em>0.3b</em>
Step-by-step explanation:
<u>Simplifying Like terms</u>
Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.
Terms like 5xy, -6xz, are not similar because they have different letters of powers.
The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus
1.6n - 0.5n = 1.1n
Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:
0.9p - 0.3p = 0.6p
Finally:
b - 0.7b = (1 - 0.7)b = 0.3b
Results:
1.1n
0.6p
0.3b
Answer:
RQ = RS = 3
Step-by-step explanation:
Since RQ and RS are radii of the circle then they are congruent
let RQ and RS be x , then
Using Pythagoras' identity in right triangle QRS
x² + x² = (3 )²
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = = 3
Thus RQ = RS = 3
