Answer:
n² - 6n - 16
Step-by-step explanation:
As per the question,
We have been provided the equation
(n-8)(n+2)
To find the product, we have to multiply the both term,
(n - 8) (n + 2)
= n (n + 2) - 8 (n + 2)
= (n² + 2n) - (8n + 16)
= n² + 2n - 8n - 16n
= n² - 6n - 16
Hence, the required answer of the product of (n-8)(n+2) = n² - 6n - 16.
Answer:
3.)equal differences over equal intervals
Step-by-step explanation:
A linear function has a constant rate of change.
A rate of change is the difference in the dependent variable for every change in the independent variable.
This means it has equal differences over equal intervals.
Pythagorean Theorem: a^2 + b^2 = c^2
-A and B are legs of the triangle
-C is the hypotenuse
#1.
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10
#2.
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
c = 13
#4.
10^2 + 4^2 = c^2
100 + 16 = c^2
116 = c^2
c =
#5.
15^2 + 9^2 = c^2
225 + 81 = c^2
306 = c^2
c =
#6.
120^2 + b^2 = 150^2
14400 + b^2 = 22500
b^2 = 8100
b = 90
#7.
144^2 + b^2 = 194^2
20736 + b^2 = 37636
b^2 = 16900
b = 130
Hope this helps!! :)
