15. f(n)= 2n-3
a) =2(11)-7
=22-7
=15
=2(-6)-7
=-12-7
=-19
b) f(g)=-5x+1
= -5(41)+1
= -205+1
= -204
= -5(-16)+1
= 80+1
= 81
16x²=(4x)², 9=3², 24x=2*4x*3
so this is a perfect square: (4x+3)²
2x+4(2x+7)+3(2x+4)
2x+8x+28+6x+12
16x+40
16x+40 would be the answer you can’t solve it any further
Answer:

_____

Every point on the x-axis has y-coordinate 0.
Let y = 0, and solve for x.
y = -5x + 5
0 = -5x + 5
5x = 5
x = 1
The line crosses the x-axis at x = 1.
