As you can see there is a negative sign befor 3x. That means 3x is a negative value. Therefore, in order to place it as first left value you would take -3x and put it before +12 ( since there is no negative sign before 12, it will stay positive)
-3x+12
Hope This Helps :)
7xy-8x because you distribute the x even if there is another variable inside the parentheses

Actually Welcome to the Concept of the Congruency of triangles,
since here, two sides with a in between angle is congruent, we will use the SAS congruency,
=> Side-Angle-Side congruency .
SAS.
Answer:
hours
Step-by-step explanation:
Hi there!
<u>1) Create a proportion</u>
- The van traveled 120 miles in 7 hours
- The van travels 1400 miles in x hours


<u>2) Solve for x</u>

Multiply both sides by 1400




Therefore, it would take the van
hours to travel 1400 miles at the same speed.
I hope this helps!
F(g) = 4g+6
1. when g = 2, output f(2) = 14
answer: 14
2. output = 18
18 = 4g+6
4g = 12
g = 3
answer: 3
3.when g = 4
f(4) = 16+6=22
answer
(4,22)
4. when input = 6 means g=6
f(6) = 24+6 = 30
different = 30-6 = 24
answer: 24
