Answer:
Step-by-step explanation:
Distributive property: a(b +c) =(a*b) + a*c
12(7n - 4) =12*7n - 12*4
= 84n - 48
number near x^2 is a
number near x is b
and number with no x is c
-5+-1/2
than you have 2 answers
1.
x=-5-1/2
x=-3
2.
x=-5+1/2
x=-2
Hope it helps
You can solve this by linear equation system
number of students (x) is 240
number of adults ( y) is 25
the picture shows the work
good luck
B because congruent means all sides and angles are the same.
Answer:
support: 25%*100 > 10%*50
