Area of shaded region = Area of triangle ABC - Area of triangle XBY
Area of triangle ABC = (6) (6) / 2 = 18 cm^2
Area of triangle XBY = (4) (4) / 2 = 8 cm^2
Area of shaded region = 18 - 8 = 10 cm^2

Answer:
4x^2 + 3x - 9
Step-by-step explanation:
First, add together functions R(x) and S(x). Stack them vertically and combine like terms:
R(x) = 2 - x^2
S(x) = 2x + 5
------------------
(R+S)(x) = -x^2 + 2x + 7
Now subtract the above result from Q(x):
Q(x) - (R(x) + S(x)) = 3x^2 + 5x - 2 + x^2 - 2x - 7, or 4x^2 + 3x - 9

What is system of linear equations?
A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.
What is substitution method?
The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.
According to the given question.
Cost of one packet of basil seeds = $1.50
Cost of one packet of squash seeds = $2.50
Cost of 18 packets of seeds = 38
Also, b represents the number of packets of basil seeds and s represents of numbers of squash seeds.
Therefore, from the given conditions we get some system of equations
and
From equation (i)
Substitute the value of s in the equation (ii)
⇒

So,
Hence, there are total 11 packets of squash seeds and 7 packets of basil seeds.

Answer:
Step-by-step explanation:
b+s=18
s=18-b
1.50 b+2.50 s=38
multiply by 4
6.00 b+10.00 s=152
divide by 2
3 b+5 s=76
3 b+5(18-b)=76
3 b+90-5 b=76
-2b=76-90
-2b=-14
divide by -2
b=7
s=18-7=11

Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260

-Hope this helped :)
250*1.04=260 or 259.9975 if you want to be technical
