Answer:
15a+12ac+6ab
Step-by-step explanation:
3a(5 + 4c + 2b)
5*3a = 15a
4c*3a = 12ac
2b*3a = 6ab
Answer:
y = 3x - 14
Step-by-step explanation:
Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.
Plug in the slope and given point into y = mx + b, then solve for b:
y = mx + b
4 = 3(6) + b
4 = 18 + b
-14 = b
Plug in the slope and y intercept into y = mx + b
y = 3x - 14
So, the equation of the line is y = 3x - 14
An explanation for 4 < x < 7 is that 4 is less than and x is less than 7.
<h3>How to explain the information?</h3>
The mathematical expression that is given is 4 < x < 7. It should be noted that this implies that 4 is less than and x is less than 7.
In this case, the appropriate values that can fit x in this situation will be 5 and 6.
