A rectangle with width 1.6 centimeters is enlarged to a rectangle with length 25 centimeters and width 8 centimeters. What is the area of the original rectangle? 8 cm² 20 cm² 25 cm² 40 cm²

Hey there! I'm happy to help!

We see that the width goes from 1.6 to 8. How much bigger is 8 and than 1.6?

8/1.6=5

8 is 5 times bigger than 1.6, so this rectangle is 5 times larger than the original. Let's find the area of the big triangle.

25(8)=200

And then divide by 5. This will give us the smaller triangle.

200/5=40

Therefore, the answer is 40 cm².

Have a wonderful day! :D

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
