[5(14 - 2)²]/2 = (5 · 12²)/2 = (5 · 144)/2 = 720/2 = 360

u + xy
u = 18; x = 10; y = 8, subtitute
18 + 10 · 8 = 18 + 80 = 98
6.
A = 479 ft²;
a - length of a side
A = a²
therefore
a² = 479 ⇒ a = √479 ⇒ a ≈ 21.886 ⇒ 22 (ft)

(7 + 5) + 4 · 13 - 2 = 12 + 52 - 2 = 64 - 2 = 62

Answer:
<h2>i. $26.16</h2><h2>ii. He cannot afford the video game</h2>
Step-by-step explanation:
Step one:
given
selling price = $48
discount is 50%
tax= 4.5%
Step two:
let us first compute the amount in discount
=50/100*48
=0.5*48
=$24
also, let us compute the tax added
=4.5/100*48
=0.045*48
=$2.16
The total amount Garry has to pay is
=48-24+2.16
=$26.16
Step three:
If he has $25, he cannot afford the video game, he will have a deficit of $1.16
