First find the area in terms of square units. The shaded area is going to be the area of the rectangle minus the unshaded area inside the rectangle. The area of the rectangle is 5*7 which is 35. For the area of the unshaded part, you can just count the squares to get 11. 35 - 11 is 24 so the area is 24 units squared. Every square unit is equal to 5 square meters, so multiply that by five to get 120 meters squared.

To get you started: Look at the bottom 4 white squares. Each square represents an area of 5 sq. meters. Thus, these 4 white squares represent an area of 4(5 sq m) = 20 sq m.

Use the same method to calculate the remaining area. Hint: I count 7 full squares in this "remaining area."

|Ax ( By − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2

=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.

Look at this set of ordered pairs:

forsale [732]

Answer: Yes

If I remember correctly, I believe these ordered pairs indicate a function, as there is exactly 1 output for every input (i.e., (output, input)). If there were 2 inputs of the same number, that'd make this relation not a function.

What values of c and d make the equation true?

saul85 [17]

Answer:

Third option.

Step-by-step explanation:

You need to cube both sides of the equation. Remember the Power of a power property:

$(a^m)^n=a^{mn$

$\sqrt[3]{162x^cy^5}=3x^2y(\sqrt[3]{6y^d})\\\\(\sqrt[3]{162x^cy^5})^3=(3x^2y(\sqrt[3]{6y^d}))^3\\\\162x^cy^5=27x^6y^36y^d$

According to the Product of powers property:

$(a^m)(a^n)=a^{(m+n)$

Then. simplifying you get:

$162x^cy^5=162x^6y^{(3+d)}$

Now you need to compare the exponents. You can observe that the exponent of "x" on the right side is 6, then the exponent of "x" on the left side must be 6. Therefore:

$c=6$

You can notice that the exponent of "y" on the left side is 5, then the exponent of "x" on the left side must be 5 too. Therefore "d" is:

$3+d=5\\d=5-3\\d=2$
