Answer:
Step-by-step explanation:
(3x - 3)(x^2 + 3) = 3x^3 + 9x - 3x^2 - 9
3x^3 = 3x^2 + 9x - 9
answer is C

Answer:
8.49 inches
Step-by-step explanation:
x^2 + 7^2 = 11^2
x^2 + 49 = 121
X^2 = 121 - 49
x^2 = 72 (then take square root on both sides)
x = 8.49 inches
Answer:
(1/3)/(1/3)=3/3=1
(1/3)/(1/3)=3/3=1ms-1
u get the speed or velocity by dividing the y axis(metres) over x axis(seconds)
which is metres (m)/seconds (s)= ms-1
so
take from the graph the differences of y axis divided by that of the x axis
1/1=1ms-1
answer on apex is 36pi squared
