Answer:
bill = 6
hoang = 14
Step-by-step explanation:
the following equations can be formed from the question
H = 8 + b eqn 1
h - 2 = 2b eqn 2
make h the subject of the formula in eqn 2
h = 2b + 2
2b + 2 = 8 + b
collect like terms
2b - b = 8 - 2
b = 6
h = 8 + 6 = 14
Here is your answer
(a+b+c)^2= a2+b2+c2+ 2(ab+bc+ca)
(a+b+c)^2= 35 + 2×23= 35+46
(a+b+c)^2= 81= 9^2
(a+b+c) = 9
