Answer:
10x(2x+1)
Step-by-step explanation:
20x^2+10x
2*10*x*x + 10 *x
Factor out the common terms
10x(2x+1)
The midpoint formula is x1+x2 divided by 2 minus y1+y2divided by 2. You should get your midpoint as a coordinate in the form of (x , y)
Area inside the semi-circle and outside the triangle is (91.125π - 120) in²
Solution:
Base of the triangle = 10 in
Height of the triangle = 24 in
Area of the triangle = 

Area of the triangle = 120 in²
Using Pythagoras theorem,




Taking square root on both sides, we get
Hypotenuse = 23 inch = diameter
Radius = 23 ÷ 2 = 11.5 in
Area of the semi-circle = 

Area of the semi-circle = 91.125π in²
Area of the shaded portion = (91.125π - 120) in²
Area inside the semi-circle and outside the triangle is (91.125π - 120) in².
Answer:
29.2%
Step-by-step explanation:
The fraction of students with black hair is 7/24. To convert that to a percentage, multiply by 100%.
7/24×100% = 29.1666(repeating)% ≈ 29.2%
6 seconds at 20 feet per second is 6x20= 120
She's was at 350 feet so she started at 350-120= 230 feet when she got on the elevator
