Question

A) Find the value of 3a + 4b when a = 17 and b = 9.

b) Use the formula v= u + at to find the velocity, when
• the initial velocity is 3 m/s
• the acceleration is 1.5 m/s2
• the time is 7 seconds​

Answer 1

A. 87

B. i dont uderstand velocily sorry

Explanation:

3*a=3*17=51

4*b=4*9=36

51+36=87

Answer 2

A) 87 = 3(17) + 4(9)
B) v= 13.5m/s
v = 3 + (1.5x7)
