Step-by-step explanation:
Because 3x7=21.
A single drink would cost be $1.55. This is because:
13 + 4x - 6 = 13.20.
(13.20 - 13 + 6) = 6.20.
6.20 / 4 = 1.55
Hope this helped.
It makes and obtuse right triangle.
Answer:
8 = 2^3, 52 = 2^2 * 13
Step-by-step explanation:
8 = 2 * 2 * 2 = 2^3
52 = 2 * 2 * 13= 2^2 * 13
<span>2x^2+8x-7=-2
</span><span>2x^2+8x - 5 = 0
using the formula:- x = [-8 +/- sqrt(8^2 - 4*2*-5) ] / 4
= -2 +/- sqrt 104)/2
= 0.5495 , -4.549
