Answer:
Step-by-step explanation:
speed=distance /time=0.9/2.5=90/25=3.6 m/s
X^2 + 9x^2
----------- = 16
(x + 3)^2
multiply each term by (x + 3)^2:-
x^2(x + 3)^2 + 9x^2 = 16(x + 3)^2
x^2( x^2 + 6x + 9) + 9x^2 = 16x^2 + 96x + 144
x^4 + 6x^3 + 18x^2 = 16x^2 + 96x + 144
x^4 + 6x^3 + 2x^2 - 96x - 144 = 0
This is difficult to solve algebraically so I drew a graph There are 2 real roots
x = -1.65 and x = 3.65 to nearest hundredth
Answer:
x = constant ( other than 5)
Step-by-step explanation:
The slope of a line x=5 is undefined
Parallel lines have the same slope
So any line that is vertical ( slope undefined) will be parallel
7 can go into 35 5 times so 5 times 5 = 25
so a=25 HOPE I HELPED
