Answer:
32
Step-by-step explanation:
(-8 × -6) - 4²
48 - 4²
48 - 16 = 32
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Your answer would be 23.85 but I presume they rounded up so it would be 23.9
Answer:
22,203 ft^2
Step-by-step explanation:
The area of a triangle with angle ∅ and two sides a and b is;
Area A = 1/2 × absin∅ ......1
The park is in the shape of a triangle, with two sides and an angle given;
Given;
a = 190 ft
b = 235 ft
∅ = 84°
Substituting the values into equation 1;
Area of the park;
A = 1/2 × 190 × 235 × sin84°
A = 22,202.70131409 ft^2
A = 22,203 ft^2 (to the nearest whole number)
Area of the park is 22,203 ft^2
You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3
