Answer:
a) 87
b) 13.5
Step-by-step explanation:
for the first question we've been given the equation and the parameters needed
so we just input the parameters
3a+4b when a is 17 and b is 9
therefore the answer is 3*17 + 4*9
51+36=87
second question
that's an equation of motion and we've been given all the parameters we also need so we just input the parameters In the equation
v=u+at
v=3+1.5*7
v= 3+10.5
v=13.5
