Answer:
No, they are not equal.
Step-by-step explanation:
f(n) = f(n-1)
Let's say, n = 3. Let's put that in the equation:
f(3) = f(3-1)
f(3) = f(2)
Are they the same? Apparently, no. So, these two functions are not equal.
x = 239
y = 146
Step-by-step explanation:
Let two numbers be x and y
x + y = 385. ------------equation (1)
x - y = 93. ------------equation (2)
from (1) and (2)
x = 239 and y = 146
The computation of the equation shows that the answers will be:
12. 340 units
13. 2(270) + (2 × x) = 690
14. x = 5
<h3>How to compute the equations?</h3>
12. The first equation that's given will be:
(13.50 × x) - (3.65 × x) = 3349
13.50x - 3.65x = 3349
9.85x = 3349
x = 3349/9.85
x = 340
The number to break even is 340 units
13. The equation that can be used to find the perimeter will be:
2(270) + (2 × x) = 690
540 + 2x = 690
2x = 690 - 540
2x = 150
x = 150/2 = 75
14. x + x + 2 + 8 = 20
2x + 10 = 20
2x = 20 - 10
2x = 10
x = 10/2
x = 5

Answer:
Not a right-angle triangle
Step-by-step explanation:
15² = 12² + 8²
225 = 144 + 64
225 = 208 is a false statement
So not a right angle triangle
Answer:
See below.
Step-by-step explanation:
- Height of the prism = <u>9 cm</u>
- Volume of prism = 3 x 3 x 9 + 3 x 6 x 9 = 81 + 162 = <u>243 cm³</u>
- Total Surface Area = 9 x 6 + 6 x 9 + 9 x 3 + 9 x 3 + 9 x 3 + 9 x 3 + 3 x 3 + 3 x 6 + 3 x 3 + 3 x 6 = 2 x 54 + 4 x 27 + 2 x 9 + 2 x 18 = 108 + 108 + 18 + 26 = 216 + 44 = <u>260 cm²</u>
