<h3>Answer:  4368 square feet</h3>

======================================================

Explanation:

Check out the diagram below

I drew a rectangle with dimensions 56 ft by 78 ft.

Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8

The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point

  • In the upper left corner, we have an area of 50*70 = 3500. Note how this is basically 5*7 = 35, but we tack on the two zeros (from 50 and 70 combined)
  • In the upper right corner, we have an area of 70*6 = 420
  • In the lower left corner, we have an area of 50*8 = 400
  • In the lower right corner, we have an area of 6*8 = 48

Add up all the areas found: 3500+420+400+48 = 4368

As a way to check, using your calculator shows that 56*78 = 4368

Guys plsss i need help. It needs work too

Answer:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

Step-by-step explanation:

We are given: f(x)=x^2+2x

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h

Finding f(x+h) we get:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

The per capita consumption of red meat by people in a country in a recent year was normally​ distributed, with a mean of 107107
Pachacha [2.7K]

Answer:

mean sample is 9.26

Step-by-step explanation:

Given data

mean = 107 pounds

standard deviation = 39.3 pounds

no of sample (n) = 18

to find out

sample means

solution

according to question we know mean of sample = 107 pounds

so standard error of this sample will be standard deviation / \sqrt{n}

now put all value n and standard deviation and we get sample mean i.e.

mean sample = standard deviation / \sqrt{n}

mean sample =  39.3 / \sqrt{18}

mean sample = 9.26
