Answer: After 12 weeks they will both be at the dentists on the same Tuesday
Step-by-step explanation:
Since we have given that
He goes for a checkup every fourth Tuesday and his friend goes for a check up every third Tuesday.
We need to find the number of weeks they both will be at the dentist on the same Tuesday.
For this we will find "L.C.M. of 4 and 3 " =12
So, After 12 weeks they will both be at the dentists on the same Tuesday.
Answer:
39 + 2x
Step-by-step explanation:
<span>mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you
can only add like terms( like terms are terms that are same name like x
or y are differnt, and like terms have same power exg x^2 and x^3 and
x^1/2 and such
I will oly put the naswers because I don't have much time
first one: 2a+3b+2c
second one: remember that -(-6c)=+6c so the answer is c-10a-2b
third one: -a-8b-5c

The x coordinate of S will be 1/2 * 2a = a.
and since the half triangle is 30-60-90 the y coordinate will be sqrt3 a
so S is (a , sqrt3a)
