5x+ 10+ 15y
= 5*x+ 5*2+ 5*(3y)
= 5*(x+2+3y)
The final answer is 5(x+2+3y)~
Answer:
x=2
y=4
Step-by-step explanation:
Explanation is in picture
Answer:

Step-by-step explanation:
We have been given the intersection coordinates:
(7,1,-6) and perpendicular to the line x=-1+t ,y=-2+t and z=-1+t
From the condition of perpendicularity we know:


Now, we have given x=-1+t , y=-2+t and z= -1+t





Now, substituting t in the given coordinates x,y and z we get:


And 
Answer:
Option 2 -
is the slope of the equation.
Step-by-step explanation:
Given : Equation 
To find : What is the slope of the line represented by the equation ?
Solution :
The slope form of line is 
Equation 
Take 2x to another side,

Divide 3 both side,


On comparing with general equation,
is the slope of the equation.
Therefore, option 2 is correct.
First we need to find the volume of the closet
V=l*w*h
V=3*3*7
V=3*21
So the volume is 63
Since 67 cubic feet is larger than 63 cubic feet, the boxes won't fit
Hope this helps
