Harry created a canvas painting on a square canvas. He then placed an order for a new rectangular canvas. The side length of the
sveta [45]

Answer:

1.x^2

2.x+8

3.x

4. 8x

Step-by-step explanation:

Length of old is x inches.

Because it is square we have that area of the old canvas : x^2

When we read : width of new is increased by 8 so : x+8

Length is x.

The difference of areas:

Old canvas : A1=x^2

New canvas : A2=x(x+8)=x^2+8x

Now we can find A2-A1:

x^2+8x-x^2=8x

Explain why |−3| + |9| represents the distance between the points (−3, −5) and (9, −5). brainly
forsale [732]
Since -5 and -5 are the same number, they are on the same y axis so the only distance we need to calculate is between the X coordinates.

When looking for distance, you can not have a negative. what |-3|+|9| is looking for is the distance from 0 on the X axis. since distance can't be negative, (you go 3 miles away from your house in one direction, vs 3 miles in the opposite. both ways is positive, even with opposite directions. same with axis, it doesnt matter which way, only the number.) you need the absolute value of -3 to get the distance from the 0 on the x axis. 

short version: distance is positive, and its adding the distances from the x axis to get distance from each other

Then we can find the mean and the standard deviation with the following formulas:

> mean(a)

[1] 50.72451

> sqrt(var(a))

[1] 7.470221

Step-by-step explanation:

For this case first we need to create the sample of size 20 for the following distribution:

X\sim N(\mu = 50, \sigma =6)

And we can use the following code: rnorm(20,50,6) and we got this output:

> a<-rnorm(20,50,6)

> a
