$AB = \sqrt{ ({3 - ( - 2)})^{2} + ({4 - 0})^{2} } \\$

$AB = \sqrt{ ({3 + 2})^{2} + {4}^{2} }$

$AB = \sqrt{ {5}^{2} + {4}^{2} }$

$AB = \sqrt{25 + 16}$

$AB = \sqrt{41}$

$AB = 6.403$

$AB = 6.4$

The absulote value of -8 and 5

Blababa [14]

The absolute value of -8 is 8 and the absolute value of 5 is 5. Absolute value is basically the number's distance from 0 on a number line, basically how many numbers it is away from 0. For that reason, it's always positive, regardless of whether or not the number is positive or negative. Hope this helped!

I don’t know how to solve this

snow_lady [41]

First you have to find the area of the WHOLE BOX. So you multiply,
8×7=56
Then find the area of the small box,
5×4=20
It says take away the area of the small box from the whole box and you should do just that: 56-20=36
The area of the shaded region is 36cm²
