3. 16) 54cm^2

   17) 16cm^2

   Step-by-step explanation:

   16) b² + h² = H²

   12² + h = 15²

   144 + h = 225

   h = 225 - 144

   h = √81

   h = 9

   A = 1/2 x b x h

   A = 1/2 x 12 x 9

   A = 54cm²

   17) same method as no 16

   h + 9 = 25

   h = 25 - 9

   h = √16

   h = 4

   A=1/2 x b x h

   A = 1/2 x 3 x 4

   A = 16cm²

4. x = 1.875

   Step-by-step explanation:

   Step 1:  Distribute

   1/2x + 3/2(x + 1) - 1/4 = 5

   1/2x + 3/2x + 3/2 - 1/4 = 5

   Step 2:  Combine like terms

   4/2x + 6/4 - 1/4 = 5

   2x + 5/4 = 5

   Step 3:  Subtract 5/4 from both sides

   2x + 5/4 - 5/4 = 5 - 5/4

   2x = 3.75

   Step 4:  Divide both sides by 2

   2x / 2 = 3.75 / 2

   x = 1.875

    x = 1.875

5. 33 1/3%

   Step-by-step explanation:

   When you roll a die, the possible outcomes are 1,2,3,4,5,6

   getting a number less than 5: 1,2,3,4

   P( getting a number less than 5)

            = number of outcomes that meet conditions / total outcomes

            =4/6

              = 2/3                                            

   Then we flip a coin  heads or tails

   We want heads

   P (heads)  = number of outcomes that meet conditions / total outcomes

       = 1/2

   Since the event outcomes do not depend on each other

   P( getting a number less than 5) *P (heads) = 2/3 * 1/2 = 1/3

   as a percent

   = 33 1/3%

6. You're in luck !  Momentum is the product of (mass) times (velocity). 

   So if you're given mass and velocity, simply multiply them, and voila,
   you have the momentum.

7. all real numbers

   Step-by-step explanation:

   simplify each side of the inequality

   26 + 6b -- already fully simplified

   2(3b + 4) → 6b + 8

   26 + 6b ≥ 6b + 8

   subtract 6b from both sides

   26 ≥ 8

   since this expression is true (26 is greater than 8), then the solution is all real numbers. any value could take the place of b because in the end, it will be canceled out by itself, resulting in 26 ≥ 8
