Answer: 2x^2-7x-15
Step-by-step explanation:
reorder the terms (x*2+3)*(x-5)
multiply the parentheses
(2x+3)*(x-5)
collect like terms (2x^2-10x+3x-15)
product= 2x^2-7x-15

Answer:
Δ AXY is not inscribed in circle with center A.
Step-by-step explanation:
Given: A circle with center A
To find: Is Δ AXY inscribed in circle or not
A figure 1 is inscribed in another figure 2 if all vertex of figure 1 is on the boundary of figure 2.
Here figure 1 is Δ AXY with vertices A , X and Y
And figure 2 is Circle.
Clearly from figure, Vertices A , X and Y are not on the arc/boundary of circle.
Therefore, Δ AXY is not inscribed in circle with center A.
Answer:
123.25
Step-by-step explanation:
Am = 4 hours
4x14.5= 58
Pm = 4 hrs 30 mins
4x14.5=58
Then multiply 30(14.5) which gives you 435. Then divide by 60. That gives you 7.25
You could also divide 14.5 by 2 since 30 minutes is half of an hour.
Then add
58+58+7.25
123.25
