Answer:
x=32
Step-by-step explanation:
that is an isosceles triangle, meaning 2 sides are the same and 2 anlges are the same.
each traingle = 180 degrees
3x+2(x+10)=180
3x+2x+20=180
5x=160
x=32
There has been 28 years since 1985 to 2013, this becomes your x value. Plug x into the equation:
f(x) = (.65*28)+24.75
f(x) = 18.2+24.75
f(x) = 42.95
Question 4 is 73 degrees. Question 5 is 60 degrees. Question 6 is 83 degrees. Question 7 is 50 degrees. Question 8 is 61 degrees. Hope this helps!(;
Answer:
[x+(4-i)][x+(4+i)]
Step-by-step explanation:
Complete the square then regroup the first two terms. Add and subtract: (b/2)^2=(8/2)^2=16
x^2+8x+17=(x^2+8x)+17
=(x^2+8x+16)+17-16
=(x+4)^2+1 create a difference of squares using i^2= -1
=(x+4)^2 - (-1)
=(x+4)^2 - i^2 use the difference of two squares identity
=[(x+4) - i][(x+4)+i]
=[x+(4-i)][x+(4+i)]
