Answer:
n²-5n
Step-by-step explanation:
The sum of the nth term is expressed as;
Sn =n/2[2a+(n-1)d]
Given
a, = -4; d = 2; n = 16
Sn = n/2[2(-4)+(n-1)2]
Sn =n/2[-8+2n-2]
Sn = n/2[2n-10]
Hence the sum of the nth term is 2n²-10n/2
2n(n-5)/2
= n(n-5)
= n²-5n
The sum of the nth term is n²-5n

Find the length of AB.
Answer:
We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units
Answer:
AB=9
Step-by-step explanation:
[tex]\frac{DC}{BC}=\frac{EC}{AC}\\ \frac{4}{3}=\frac{16}{AC}\\\\ AC=12\\\\ AB=AC-BC\\ AB=12-3=9[/tex]

The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape
Answer:
[tex](3x+1)[/tex]
[tex](x+4)[/tex]
Step-by-step explanation:
Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.
[tex]3x^2 + 13x + 4[/tex]
Just by looking at the polynomial, it is fairly obvious that the factors are;
[tex](3x+1)(x+4)[/tex]
One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,
[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]
Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;
[tex](3x+1)\\\\(x+4)[/tex]
Solve the system of equations using the substitution method. 2x+y=8
y=x-1
Answer:
x=3
Step-by-step explanation:
If we know that y=x-1, we can just substitute it and replace y with (x-1)
so 2x+y=8 becomes:
2x+(x-1)=8 and we simplify that into:
3x-1=8, add 1 on both sides to make it:
3x=9, divide 3 on both sides
x=3
