Answer:
x = -1.75 , +/- 1.1892i.
Step-by-step explanation:
4x5 + 7x4 + 36x + 63) = (4x + 7)
4x^5 + 7x^4 + 32x + 56 = 0
x^4(4x + 7) + 8(4x + 7) = 0
(x^4 + 8) = 0 or 4x + 7 = 0
4x + 7 = 0
x = -1.75.
4x^4 = -8
x^4 = -2
x = +/- ⁴√-2
x = +/- 1.1892 i.
Answer:
<em>15 people</em>
Step-by-step explanation:
since Raul and his friends each weigh 1/20 ton,
and the total weight reads 3/4 ton
The total number pf people on the scale will be:
<em>The total weight of Raul and his friends divided by their individual weight</em>
==> (3/4 ton) ÷ (1/20 ton)
= 3/4 X 20/1 = <em>15 people</em>
25.5
102/4=25.5
Not really sure though
