3x+3 = x-1
2x+3 = -1 (subtracted x from both sides)
2x = -4 (subtracted 3 from both sides)
x = -2 (divided 2 from both sides).
As you know a square has all of its sides equal and has four sides.To find the area,you have to know what the height and the width is.Well,we already know from the problem that one side is 58 in and as i said before all sides of a square are equal length.So the height and width would both be 58 in.Now we have to multiply the height and the width.58*58=3364.So, the area of the square is 3364 in.
Answer:-8.1111111
Step-by-step explanation:
Surface area is what it seems to be. All of the area of the solid's faces together. Like a cube, just find the areas of all of the squares that make the cube then add them together.
Answer:
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.
Step-by-step explanation:
We want to calculate the area under the curve within 3 standard deviations from the mean.
If we use the standard normal distribution, this probability can be calculated as the diference between P(z<3) and P(z<-3).
The area under the curve for the standard distribution and for any normal distribution within 3 standard deviation from the mean is 0.9973.
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.
