Answer:

The answer is x² + x - 12.

Step-by-step explanation:

1) Use foil method: (a + b) (c + d) = ac + ad + b + bd.

{x}^{2}  - 3x + 4x - 12

2) Collect like terms.

{x}^{2}  + ( - 3x + 4x) - 12

3) Simplify.

{x}^{2}  + x - 12

<u>hence</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>x</u><u>²</u><u> </u><u>+</u><u> </u><u>x</u><u> </u><u>-</u><u> </u><u>12</u><u>.</u>

inn [45]

Answer:

1) n^2 – 3 n + 8   4^2 – 3*4 + 8 = 12    

2)    (x^2 – 4 y) / 2      (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36     Abs -9 = 9  

4) 19 – x^2 = 19 – 25 = -6     (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) =  - 20      (-2)^3 = -8

Brandon enters bike races.He bikes 8 1/2 miles every 1/2 hour. complete a table to find how far Brandon bikes for each time inte
MissTica
12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking. SO here are the data that we need: => 8 and ½ miles = 8.5 miles => ½ hour = .5 hours or 30 minutes Now, let’s solve for the unit rate => SO in every 30 minutes he bikes around 8.5 miles => Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2 => 8.5 * 2 = 17miles => 17 miles / hour
