Please help! math! 10 points was the max:( <br> will give brainliest!!
Nezavi [6.7K]

It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm

{4}^{2}  + {5}^{2}  =  {41}^{2}

\sqrt{41}  = 6.403124237

An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).

Multiply the terms in the first parenthesis by - 3 and the terms in the second parenthesis by - 2

= - 12x - 15 + 10x - 16 ← collect like terms

= (- 12x + 10x) + (- 15 - 16)
