Answer:
125
Step-by-step explanation:
GCF of 12,18 = 6
LCM of 12,18 = 36
I cant type it out so here is a photo
Answer:
(-3, -5)
Step-by-step explanation:
By using the distance formula, we see that the length of RT is 
which equals 
.
The ratio of RS to ST is 3:2, so we can write the distance of RS as 
which equals 
. The distance of ST is then 
.
Since we know the distance of RS and ST, we can find the coordinates of point S by using the distance formula again:
and 
We solve for x and y, getting (-3, -5).
Answer: c=5.4
The two roots are 3/5 and 9/5
Step-by-step explanation:
assume 5x2−12x c=0 is supposed to be 5x^2 - 12x + c = 0
p = (12 + sqrt(144-20c))/10
q = (12 - sqrt(144-20c))/10
p-3q=0,
1.2 + 0.1sqrt(144-20c) +
-3.6 + 0.3sqrt(144-20c) = 0
-2.4 + 0.4sqrt(144-20c) +2.4 = 2.4
sqrt(144-20c) = 2.4/0.4 = 6
144-20c=36
144-36=20c
c = 108/20 = 5.4
5x^2-12x+5.4=0
x = 3/5 or x = 9/5
