Step-by-step explanation:

area of first triangle =1/2×112×202×sin30°

  • 1/2×112×202×1/2
  • 5656m²

area of second circle=1/2×202×197×sin60.5°

  • 1/2×202×197×0.870
  • 17310.39m²

Total area of estates=area of first triangle +area of second triangle

  • 5656+17310.36
  • 22966.39m²

hope it helps.

Jenny thinks that the expression below is equal to x²-4. If you agree, show that she is correct. If you disagree, show that she
sergiy2304 [10]

Answer:

Jenny is wrong the correct answer is x²+ 4 - 4 x.

Step-by-step explanation:

Given that

(x-2)³∕x-2

(x-2)³∕(x-2) =(x-2) (x-2)²∕(x-2)

(x-2)³∕(x-2) = (x-2)²

As we know that

(a-b)² = a²+b² - 2 ab

So

(x-2)² = x²+ 2² - 2 ˣ 2 ˣ x =  x²+ 4 - 4 x

(x-2)² =  x²+ 4 - 4 x

It means that

(x-2)³∕(x-2) = (x-2)² =  x²+ 4 - 4 x

So Jenny is wrong the correct answer is x²+ 4 - 4 x.

How to check division with multplication<br><img src="https://tex.z-dn.net/?f=3%20%5Ctimes%20292%20" id="TexFormula1" title="3 \
svetoff [14.1K]

Answer:  By cross multiplication.

Step-by-step explanation:  Given product is 3 × 292.

We know that after simple multiplication, we get  3 × 292 = 876.

Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,

or

we need to divide 876 by 292 to get the answer 3.

We will do that as follows -

\dfrac{876}{3}=292~~~\textup{and}~~~\dfrac{876}{292}=3.

Thus, doing cross-multiplication, we arrive at our conclusion.

What is the solution to the equation 13.7y = 6.2y + 30?
il63 [147K]

Here, we are required to determine the solution to the equation: 13.7y = 6.2y + 30?

The solution to the equation is y = 7.5

The solution is thus,

  • 13.7y = 6.2y + 30
  • 13.7y - 6.2y = 30
  • 7.5y = 30

Therefore, y = 30/7.5 = 4

Therefore, y = 4 is the solution to the equation.
