Answer:
45
Step-by-step explanation:

ssubstitute a and b for any of the numbers (3 or 6) and get 36+9 which is 45
45 =

so you would need to find the square root to get c
Answer: However, in real life it depends on the shape of the actual presents. If two sheets are used for the 2 presents. There should be enough left from those sheets to use for the third present. (They should be taped together.)
Step-by-step explanation: 6/3 then 3 over 8 ––> 3/8
6/ 27/8
= 6/1 / divide 27/8
= 6^2 /1 x 8/27 ^9 (^) –––> this mean square root of 2 or 9
6 cancels and 27 cancel
= 16/9
=1 7/9
However you will still need to buy 2 sheets
Answer:
Time taken n = 19 years (Approx)
Step-by-step explanation:
Given:
Amount of car P = $27,500
Decrease rate r = 15% = 0.15
Final amount A = $1,254
Find:
Time taken n
Computation:
A = P[1-r]ⁿ
1,254 = 27,500[1-0.15]ⁿ
0.0456 = [0.85]ⁿ
Time taken n = 19 years (Approx)
Answer:

Step-by-step explanation:
Add up all the sides to get the perimeter:

Answer:
parallel
Step-by-step explanation:
The answer is parallel because Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines
