The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle

Answers

Answer: x+5 or ((x^2+8x+15)/(x+3))

Step-by-step explanation: First let's assign our variables.

x^2+8x+15 = Area

X+3 = Width

? = Length

If the equation of a=lw, then we can substitute in our variables.

a=lw

x^2+8x+15= L (x+3)

Now we must isolate L.

Divide both sides of the equation by 'x+3'

x^2+8x+15= L (x+3)

x+3                 x+3

x+5= L

Answers

Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b, where m - slope, b - y-intercept

We are given two points on the graph:

(0, 1) and (2, 0)

The first point gives us the y-intercept:

b = 1

Finding the slope using slope formula:

m = (y2 - y1)/(x2 - x1)m = (0 - 1)/(2 - 0) = -1/2

The formula of the line:

y = -1/2x + 1

Answers

Answer:

y = 15

y = -10

Step-by-step explanation:

y=-5x

y= -5(-3)

= 5 × 3 = 15

y = 15

y = -5x

y = -5(2)

y = -5 × 2

y = - (5 × 2)

5 × 2 = 10

y = -10

4x - 3y = -3
4x + y=17
The solution is....

Answers

1. Subtract the second equation from the first and solve for y: 0 - 4y = -20 => y=5
2. Substitute y=5 into one of the equations and solve for x: 4x - 3(5) = -3 => 4x = 12 => x=3

So the solution is (x, y) = (3, 5)

Answer:

Step-by-step explanation:

Hello There!

Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180

So we setup an equation

180=2x+12+5x

step 1 combine like terms

5x+2x=7x

now we have

180=7x+12

step 2 subtract 12 from each side

12-12 cancels out

180-12=168

now we have

168=7x

step 3 divide each side by 7

7x/7=x

168/7=24

we're left with~ x=24

How do you think statistics may at times not say something? How can a well-designed study be used to carefully say everything that is important about a population? Is it possible to do so?

Answers

Answer:

While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.

A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.
