Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
Alright, so I=prt. I is 1090-900=190=interest. It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years
Note that 1 meter = 100 centimeters, so 1.3 meters = 130 centimeters
It grew another 22 cm
130 + 22 = 152
152 cm is your answer
hope this helps
0.35 you divide the 21 feet per second and the 60 seconds in a minute to get 0.35
