Answer:

x=9

Step-by-step explanation:

a=hyp=15

b=base=12

x=perp=?

using pathagorus theorem:

{hyp}^{2}  =  {base}^{2}  +  {perp}^{ 2}  \\  {15}^{2}  =  {12}^{2}  +  {x}^{2}  \\ 225 = 144 + x \\ 225 - 144 =  {x}^{2}  \\ 81 =  {x}^{2}  \\ x = 9

Which of the following is an inequality sentence?
ziro4ka [17]

Answer:

C. x

Step-by-step explanation:

  • Option A [x+5=20]tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
  • Option B[x=5] tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
  • Option C[x tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
  • Option D[x+5] is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
