Answer:
9x^3-21x^2+19x-6
Step-by-step explanation:
First you have to distribute the first equation into the second since the two are being multiplied:
(3x^2-5x+3)(3x-2)
9x^3-6x^2-15^2+10x+9x-6
(simplify)
9x^3-21x^2+19x-6
Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430
