Actually, the equation is supposed to be 4^2/ (3+1).

So, it'd be:

4^2/ (4)

16/4

I hope this helped! :)

According to PEMDAS, the parentheses would go first.

3+1 = 2

42/2=21

Hope this helps!

Bingel [31]

Answer:

9 (make sure to place the currency symbol (e.g. £ or $) beside your answer, otherwise it may be counted as incorrect).

Step-by-step explanation:

If one adult went and the adult tickets cost 14, we can subtract 14 from 59 to see the total cost of the children's five tickets:

59 - 14 = 45

Because there are 5 children, you then divide that value by 5 in order to find out the cost for one child and, ultimately, the cost of each child's ticket: 45 ÷ 5 = 9
The cost of each child's ticket is therefore 9

Given the equation:

Alisiya [41]

Answer:

x = 1 and x = $\frac{-4}{5}$

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

x = $\frac{1+\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$ and x = $\frac{1-\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$

Now, simplify the equations:

x = $\frac{1+\sqrt{81} }{10}$ = $\frac{1+9}{10}$ = $\frac{10}{10}$ = 1

and

x = $\frac{1-\sqrt{81} }{10}$ = $\frac{1-9}{10}$ = $\frac{-8}{10}$ = $\frac{-4}{5}$
