Club A: 25+30x where x is the number of lesson
Club B 55 + 20x where x is the number of lesson
when is the cost equal
25+ 30x = 55 + 20x
subtract 20 x from each side
25+ 30x -20x = 55 - 20x
25+ 10x = 55
subtract 25 from each side
25-25+ 10x = 55 - 25
10 x = 30
divide by 10
10x/10 = 30/10
x = 3
After 3 lessons the cost is equal
A) x=-4
b) x=-7
c) x=-6.5
d) x=-5
e) x=-3
f) x=-3
g) x=-12
h) x=-4
i) x=-8
hope that helps

the perimeter of the kite:
20+20+33+33=106mm
Answer:
h(x)=x²+6 and g(x)=8x-5
prove that hg(x)=19
Step-by-step explanation:
step 1: hog(x)=h[g(x)]
step 2: h(8x-5)
step 3: h(8x-5)= (8x-5)²+6
step 4: (8x-5)(8x-5)+6
step 5: 16x² +15x +6
