What is this expression?
Liula [17]

Answer:

2) 4/3

Step-by-step explanation:

(4^-3 * 3^4 * 4^2)/(3^5 * 4^-2)

4^-3 * 3^4 * 4^2 = 4^-1 * 3^4

(4^-1 * 3^4)/(4^-2 * 3^5)

(3^4)/(3^5) = 1/(3^5-4)

(4^(-1))/(4^-2 * 3^(5-4)

(4^-1)/(4^-2 * 3)

4^(-1 - (-2)) / (3)

-1 - (-2) = 1

4/3

Can someone help me with this math problem, please? Thanks!
vichka [17]
Answer: D, -1
First, plug in the value -1 for x in f(x) first. \frac{1}{(-1)^2+1} can then be simplified to \frac{1}{2} because (-1)^2=1. Next, put the value -1 for x in the equation g(x). This will look like - \frac{1}{2}.

The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.

∠A and \angle B∠B are complementary angles. If m\angle A=(6x+3)^{\circ}∠A=(6x+3)
Wewaii [24]

Answer:

Step-by-step explanation:

The angles are complimentary, so they add to 90

6x + 3 + 7x + 9 = 90             Combine like terms

13x + 12 = 90                         Subtract 12 from both sides

13x = 90 - 12                          Combine

13x = 78                                 Divide both sides by 13

x = 6

<A = 6x + 3

<A = 6*6 + 3

<A = 36 + 3

<A = 39
