Answer:

option c. ±\sqrt{65}

Step-by-step explanation:

In the given right angled triangle we can see that :-

  • hypotenuse is 9
  • adjacent is 4
  • opposite is x

by Pythagoras theorem

hypotenuse² = adjacent ² + opposite ²

9² = 4² + x²

81 = 16 + x²

combining like terms

81 - 16 = x²

65 = x²

x = ±\sqrt{65}

Bess [88]

Answer:

5r + (5 x 6) = 84

looking for rice per pound.

Step-by-step explanation:

5r + (5 x 6)  = 84

This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.

5r + (5 x 6)  = 84

5r + (30)  = 84

5r = 84-30

5r = 54/5

r  = 10 4/5  

r  =  10.8 pounds
