Hello!
You can only add like terms
3x^2 + 4x^2 = 7x^2
2x + -5x = -3x
-8 + 6 = -2
The answer is 7x^2 - 3x - 2
Hope this helps!
Answer: 0.0825
Step-by-step explanation:
8.25% to decimal is simply divide 8.25 by 100

Answer:
B. 42 - (-26)
Explanation:
Answer:
105.12 feets
Step-by-step explanation:
From the figure x we can identify a rectangle and a semicircle :
Area of rectangle = Length * width
Area = 8 * 10 = 80 feet²
The Area of a semicircle = 1/2πr²
Radius, r = 8 /2 = 4 feets
A = 1/2 * 3.14 * 4²
A = 3.14 * 8
A = 25.12 feet²
Area of figure = 80 + 25.12 = 105.12 feets
