Answer:
You seem to have two questions, so I will answer both!
Step-by-step explanation:
The answer for the cube volume is D
If you remove a cube from another cube it is affecting more than one side, hence the -1 on two differents p's.
The true area of that house is 48m^2
Take the before scaling it, multiply it by the scale (200)
Square your answer and get around 48 m^2
(You actually get like 48.9897 etc, but we are kind of ignoring that)
X is going to be 19 if 4 is to 3
Answer:
0 solutions / no solutions
Step-by-step explanation:
If two lines have the same slope but different y-intercepts, it means that they are parallel.
For example, we have two lines:
y = x
y = x + 1
Both lines have the same slope of 1, but different y - intercepts. Because each equation increases the x and y at the same right (slope) but started at different points, the two equations will never touch.
It's similar to two runner who run at the same pace. If one runner started 50 meters ahead, that runner will always be ahead 50 meters (y-intercept) because they both run at the same rate.
