Answer:
Option A, C and D are correct.
Step-by-step explanation:
Option A is correct because if we take example of 
we get:
1,2,1
1,3,3,1
1,4,6,4,1
So we can see that either we read left to right or right to left we are getting same row
Option B is not correct because When we take power zero it will occupy first row hence, 
is not given by nth row.
Option C is correct because adding adjacent terms on a will give us the term directly below look at the example in option A.
Option D is correct because nth row will give coefficients in the expansion of (x + y) n-1 since, zero will occupy first row hence, nth row will be n-1.

sorry, but you need to show the selectings
Step-by-step explanation:
Answer:
13meters
Step-by-step explanation:
c^2=a^2+b^2
12^2+5^2=169
find squareroot of 169 which is 13meters
Answer:
B
Step-by-step explanation:
The sections of the parallel roads split by the transversals are in proportion, that is
= 
( cross- multiply )
300 first = 577500 ( divide both sides by 300 )
first = 1925 ft
Thus
Elm st → Maple st = 1925 + 350 = 2275 ft → B
Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions
<h3>Modulus functions</h3>
Modulus functions are functions that can either be positive or negative. Given the modulus function below;
|h| − 8 = 4
The modulus of h can both be negative and positive
If the modulus of h is positive then;
h - 8 = 4
Add 8 to both sides
h-8 + 8 = 4 + 8
h = 4 + 8
h = 12
If the value of h is negative
-h - 8 = 4
-h = 4 + 8
h =-12
Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions
