1 answer:

8 0

12•x^7•y^5

When multiplying, you multiply the coefficients (which would be 2 and 6 in this case) then with the exponents you add the exponents and give them to the common variable
X^4•x^3
You add 4 and 3
x^7

I hope this makes sense:)

Step-by-step explanation:

Using the sine ratio in the right triangle.

sinC = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{BC}$ = $\frac{16}{28}$ , thus

∠ C = $sin^{-1}$ ( $\frac{16}{28}$ ) ≈ 34.85° ( to 2 dec. places )

Answer:

hiii

Step-by-step explanation:

1. Multiply both sides by 3

38/3x x 3 +16/3. x =-20x3

2. Simplfy

38x+16=-60

3. Subtract 16 from both sides

38x+16-16=-60-16

4. Simplfy

38x=-76

5. Divide both sides by 38

38x/38=-76/38

6. Simplfy

x=-2
