Answer:
A = 4, B = 3
Step-by-step explanation:
You require that ...
0.30 × A = 0.40 × B
Then ...
B = (3/4)A . . . . . divide by 0.40
Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
<span>ab + bc + b</span>²<span> + ac =
(b</span>² + bc<span>)+(ab + ac) =
b(b+ c)+a(b + с) =
(b + c)(b + a)</span>
Answer:
83
Step-by-step explanation:
f(x) = 7x - 1
Put x as 12.
f(12) = 7(12) - 1
f(12) = 84 - 1
f(12) = 83
