Answer:
x = 15, 72 degrees
Step-by-step explanation:
4x + 12 + 108 = 180
4x + 120 = 180
4x (+ 120 - 120) = 180 - 120
4x = 60
4x/4 = 60/4
x = 15
4x + 12
4(15) + 12
60 + 12
72 degrees
Those are all lines...
So the x interval is from -2 to 3, because of x=-2 and x=3
The upper line is y(u)=4x and the lower line is y(l)=x-5
So the area between the two lines is:
A=⌠y(u)-y(l) dx
A=⌠4x-x+5 dx
A=⌠3x+5 dx
A=[3x^2/2+5x]
A=[(3x^2+10x)/2], x=[-2,3]
A=(1/2)(27+30-(12-20))
A=(1/2)(57+8)
A=(1/2)(65)
A=32.5 u^2
Answer:
6 because they are 6 sq apart
Step-by-step explanation:
Your answer will be 1/10. you divide 3 by the numerator and denominator <span />
3a to the power of 2 plus 5a minus 2
