X = 5 , -11\3 >>>>>>>>>>>>>>
You solve for x
start by expanding the (3x-7)²
12 = 2(3x - 7)(3x - 7) + 4
12 = 2(9x² - 42x + 49) + 4
multiply the 2 through
12 = 18x² - 84x + 98 + 4
combine all like terms, set equal to zero
18x² - 84x + 102 - 12 = 0
18x² - 84x + 90 = 0
use the quadratic equation
Where
a = 18
b = -84
c = 90
then x = 3 and 5/3
Y-axis, because what i’ve been taught with coordinates, is you crawl before you walk which means is first it’s x-axis then y-axis. so (0,4) would be on the y-axis. :)
Answer:
Claire is standing at a distance of 485.45 meters to Chloe.
Step-by-step explanation:
The track is a circular with a radius of 100 meters.
The total length of the circular track = length of the circumference of a circle
But, length of the circumference of a circle = 2r
So that,
total length of the circular track = 2r
= 2 × × 100
= 628.57
The total length of the circular track is 628.57 meters.
Thus,
the distance of Claire to Chloe = total length of the circular track - distance of Chloe to Claire
= 628.57 - 143.12
= 485.45
This means that Claire is standing at a distance of 485.45 meters to Chloe.
