Answer:

Step-by-step explanation:

m∠1 = 49° (Opposite Angles)

m∠1 + m∠2 + 68° = 180° (The sum of all interior angles of any triangle is equal to 180°)

49° + m∠2 + 68° = 180°

m∠2 + 117° = 180°

m∠2 = 180° - 117°

m∠3 + 93° = 180° (The angles on a straight line add up to 180°)

m∠3 = 180° - 93°

m∠4 + 49° = 93° (An exterior angle of a triangle is equal to the sum of its two interior opposite angles.)

m∠4 = 93° - 49°

Which expression is equivalent to 4(x^3)(2x)^-4

AVprozaik [17]

Answer:

= $\frac{4x^{3}}{16 x^{4}}$

Step-by-step explanation:

$4(x^{3} )(2x)^{-4}$

= $\frac{4x^{3}}{(2x)^{4}}$

= $\frac{4x^{3}}{2^{4} x^{4}}$

= $\frac{4x^{3}}{16 x^{4}}$

Multiply 4x(-3x - 5)

Scilla [17]

Using the distributive property the product is -12x-20. To distribute you take the numbers and or variables outside of the paranthesis and multiply it by each one in the parenthesis such that 4x is multiplied by -3x getting -12x and multiplying 4x by -5 and the product is -20x and all together the answer is -12x-20
