So you have to simplify



(9 x 10 x 18) 2 + (5 x 10 x 18) (-7) + (5 x 9 x 18)

(-11) + (5 x 9 x 10)

5 x 9 x 10 x 18

1620 x 2 + 900 (-7) + 810(-11) + 450 x 5
x 5 x 9 x 10 x 18

The answer would be -6/5

Rectangle ABCD translates 4 units down and 2 units to the right to form rectangle A'B'C'D'. The vertices of rectangle ABCD are l
AlekseyPX

The length of B'C' in the rectangle A'B'C'D' = 9 units.

<u>Step-by-step explanation</u>:

step 1 :

Draw a rectangle with vertices ABCD in clockwise direction.

where, AB and DC are width of the rectangle ABCD.

            AD and BC are length of the rectangle ABCD.

step 2 :

Now,

The length of the rectangle is AD = 5 units and

The width of the rectangle is AB = 3 units.

step 3 :

Draw another rectangle with vertices A'B'C'D' extended from vertices of the previous rectangle ABCD.

step 3 :

The length of the new rectangle is A'D' which is 4 units down from AD.

∴ The length of A'D' = length of AD + 4 units = 5+4 = 9 units

step 4 :

Since B'C' is also the length of the rectangle A'B'C'D', then the measure of B'C' is 9 units.

Priya drew a circle whose area is 25 cm. Dan drew a circle whose diameter is 4 times the radius of Priya's circle. How many time
Vitek1552 [10]

Answer:

400

Step-by-step explanation:

first work out the radius of priya's circle with the equation a = \pi r^{2}

25 = \pi r^{2}

\frac{25}{\pi } = r^{2}

r = \sqrt{\frac{25}{\pi } }

we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x\sqrt{\frac{25}{\pi } }

this means that if the diameter of dan's circle is 4 times bigger it must be

8x\sqrt{\frac{25}{\pi } }

to find the radius of dan's circle we divide the diameter by to 2 to give

4x \sqrt{\frac{25}{\pi } }

then use the a=\pi r^{2} equation again

a= (4 \sqrt{\frac{25}{\pi } })^{2} \pi

which equals 400

hope that helped
