Step-by-step explanation:
I think its shear, because that is the only one in which the shape actually changes shape and size
Answer:4π
Step-by-step explanation:
Φ=72
Radius=r=10
Length of arc=Φ/360 x 2 x π x r
Length of arc=72/360 x 2 x π x 10
Length of arc=0.2 x 2 x π x 10
Length of arc=4π
The answer is 7*5*3*4=420
2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).
