Answer:
10x + 9
Step-by-step explanation:
I'm assuming the 3x2 is 3 * x * 2
x + 3 * x * 2 + 3x + 9
x + 6x + 3x + 9
10x + 9
Answer: A
Step-by-step explanation: A, because it by the end of all of this, (A) manages to reach to the top, and B stretches across the chart/ which is considered the distance. Also if you look where the points are, you can see that point A rose quicker in shorter time.
Answer: x = 16.75
Step-by-step explanation:
I'm not good at square roots but if you divide both sides by 2:
(2x – 9) • 2 / 2 = 49 / 2
simplify:
2x – 9 = 49/2
add 9 to both sides:
2x – 9 + 9 = 49/2 + 9
simplify:
2x = 67 / 2
divide both sides by 2:
2x ÷ 2 = 67/2 ÷ 2
simplify:
x = 67/4
Answer:
x = 16.75
2/3
because 14/3= 2.66666666
14-2.666666= 9.33333333
9.333333/14= 2/3
