Answer:
3. Option No. 2:
6x + 2y = 22
3x + 3y = 18
4. Option No. 2:
$2.50
Step by step explanation:
4. 6x + 2y = 22
(3x + 3y = 18) * 2
- Negate
6x + 2y = 22
6x + 6y = 36
2y - 6y = 22 - 36
-4y = -14
y = -14/-4
y = 3.5
An order of onion rings = $3.50
- Substitute to find for x
6x + 2(3.5) = 22
6x + 7 = 22
6x = 22 - 7
6x = 15
x = 15/6
x = 2.5
An order of French fries = $2.50
It is B. simple random sample
The expression for the area of the shaded region is s^2 - pir^2
<h3>Area of composite figure</h3>
The formula for calculating the area of the shaded part in the given equation is expressed as:
Area area of square. - area of circle
Since
Area of square = s^2
Area of circle = pir^2
substitute
Area of shaded part = s^2 - pir^2
Hence the expression for the area of the shaded region is s^2 - pir^2

The correct match for each leading coefficient will be as below:-
1. ⇒ b ⇒ 8
2. ⇒ d ⇒ 4
3. ⇒ e ⇒ 40
4. ⇒ c ⇒ - 8
5. ⇒ a ⇒ 2
<h3>What is a polynomial?</h3>
A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
The leading coefficient of the polynomial is defined as the coefficient of the variable having the highest power in the polynomial.
For the given polynomials calculate the highest power variable in each polynomial with the coefficient.
1.
P(x) = (x + 2) (2x - 3) (4x +7):
P(x) = 8x³
2.
P(x) = 1/2(x - 2) (2x - 3) (4x + 7):
P(x) = 4x³
3.
P(x)= 5(x - 2) (2x - 3) (4x + 7):
P(x)= 40x³
4.
P(x) = -(x - 2) (2x - 3) (4x + 7):
P(x) = -8x³
5.
P(x) = 1/4(X + 2) (2x - 3) (4x + 7):
P(x) = 2x³
Therefore, the leading coefficients are 8, 4, 40, -8, and 2 respectively.
