<span>(3x-4)+(x+3)^2
= 3x - 4 + x^2 + 6x + 9 .........(expand using (a+b)^2 = a^2 + 2ab + b^2)
= x^2 + 9x + 5 ..........(combine like terms and simplify)
hope that helps</span>
Answer:
Part 1) The algebraic expression is equal to
or 
Part 2) The algebraic expression is equal to 
Step-by-step explanation:
Part 1) we have (n-1) increased by 110%
110%=110/100=1.10
so
The algebraic expression of (n-1) increased by 110% is equal to multiply 1.10 by (n-1)

Distributed

Part 2) we have n^(-1) increased by 110%
110%=110/100=1.10
so
The algebraic expression of n^(-1) increased by 110% is equal to multiply 1.10 by n^(-1)
Remember that

so

Answer:
Option (a)
Step-by-step explanation:
Slope of a line passing through two points
and
is given by,
Slope (m) = 
Slope of the line passing through (-4, 3) and (6, 3) will be,
m = 
m = 0
In other words, slope of any line parallel to x-axis is zero.
Therefore, Option (a) is the answer.
Answer:
a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
Step-by-step explanation:

Add 16 to both sides.


or 
or 
or 
Therefore, a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
Interest rate = 7%
I= PRT where I is the interest earned, p is the principal, r is rate as a decimal, and t is time in years.
A - P will give us the interest earned.
12,150 - 9,000 = 3,150
3150 = (9000)(r)(5)
3150 = 45,000r
r = 0.07
r = 7%
