All we can do here is assume that the width and length of the rectangle in question are 3x-2 and 4x-7.  

If and only if this assumption is correct, then the area is L * W, or

(3x-2)(4x-7) = 12x^2 -13x + 14.

To find the area, we have to use the F.O.I.L. method to solve (3x-2)*(4x-7)

-> 12x^2-21x-8x+14

= 12x^2 - 29x + 14

So the area of the rectangle would be 12x^2 - 29x + 14.

Lets just choose the first one, 3 4 and 5. According to the Pythagorean Theorem,
a^2+b^2=c^2

So lets plug in our numbers.

3^2+4^2=c^2

The answer should be 5, but lets make sure.

3*3 = 9
4*4 = 16
9+16=c^2
25 = c^2
Square root both sides so:
5=c
And sure enough 5 is the last number on that list. The order doesn’t matter as long as the value you are trying to find is the c^2.

HELP ASAP I WILL GIVE BRAINLIST
VikaD [51]

Answer:

33.51 cm

Step-by-step explanation:

240/360 = 2/3 (Arc length is 2/3 of the total circumference)

C = 2\pir             ( Calculate the total circumference)    

C = 2(8)\pi

C = 50.265

2/3(50.265)      (Take 2/3 of the circumference. times 2 divide by 3)

33.51

Use a calculator and leave the answer to C and then multiply and divide. You get a more precise answer.
