Answer:

11 r + 4 n + 8 b + 10

Step-by-step explanation:

Simplify the following:

9 r + r + 7 b + 10 + b + r + 4 n

Grouping like terms, 9 r + r + 7 b + 10 + b + r + 4 n = (9 r + r + r) + 4 n + (7 b + b) + 10:

(9 r + r + r) + 4 n + (7 b + b) + 10

9 r + r + r = 11 r:

11 r + 4 n + (7 b + b) + 10

7 b + b = 8 b:

Answer: 11 r + 4 n + 8 b + 10

prohojiy [21]

Answer:

C) 3.0

Step-by-step explanation:

Let the length of the other side be x.

Using Pythagoras theorem for right-angled triangle,

4.2^2=2.9^2+x^2

or,x^2=4.2^2-2.9^2

or,x^2=9.23

or,x=√9.23=3.0 units
