if14a^2b/7a^2b answer is 2
and if the sign is addition then the answer is21a^2b if subtraction answer is7a^2b
I'm sorry but I'm not into square roots yet :(
Hi there!
We can split into factors using the "guess and check" method.
Factors are in the format of:
(ax + b)(cx + d), where in this instance:
a · c = 2
bc + da = 5
b · d = 3
Thus, we get:
(2x + 3)(x + 1)
Answer:
The admission cost of each adult is $11.5 and that of each children is $6.5.
Step-by-step explanation:
Let the admission cost for children to the museum is $x.
So, the admission cost for adults to the museum is $(x + 5) {As per given condition}
Now, given that admission to the museum for Barbara and Jeff Johnson and their five children cost fifty-five dollars and fifty cents.
Hence, 2(x + 5) + 5x = 55.5
⇒ 7x = 45.5
⇒ x = $6.5
So, $(x + 5) = $11.5
Therefore, the admission cost of each adult is $11.5 and that of each children is $6.5. (Answer)
