Answer:
22.5 cm
Step-by-step explanation:
9 inches=9×2.5 cm =22.5 cm
We meet again
so first divide 60 by 5
this gives 12
then multiply 12 by 4
giving a final answer of 48
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 + 2 and g(x) = x^2 – 9
(f – g)(x) = 3x^2 + 2 -( x^2 – 9)
Distribute the minus sign
3x^2 + 2 - x^2 + 9
Combine like terms
2x^2 +11
Subtract 6 from both sides
15x= 195
Divide both sides by 15
x=13
Final answer: x=13
Check:
15(13)+6
195+6
201
201=201
3^3. if you're simplifying then you keep the base the smae but add the exponents since you are "multiplying" the bases
