Answer:

5x^2 + 55x

Step-by-step explanation:

Let's review f(x)g(x) simply means you multiply both functions together.

So,

(5x)(x+11)

5x * x = 5x^2

5x * 11 = 55x

Hence, the answer is 5x^2 + 55x

Answer:

C

Step-by-step explanation:

f(x) × g(x)

= 5x(x + 11) = 5x² + 55x, thus

h(x) = 5x² + 55x → C

The angles of a pentagon are in ratio
ivanzaharov [21]

Answer:

  216°

Step-by-step explanation:

The ratio of the sum of smallest and largest to the total of all angles is ...

  (9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4

__

The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...

  180°(5 -2) = 540°

Then the sum of smallest and largest angles is ...

  0.4(540°) = 216°

Can someone please help me please?
ladessa [460]

Answer:

B

Step-by-step explanation:

F(x) is just a negative vertical shift downwards, so when you have a downwards shift the number of units down is placed right after the x outside of the parenthesis. In this case, there was a shift of -4, so it would be -x^2 - 4.
