Answer:

27.6

Step-by-step explanation:

1) Say bens depth is x

Cam's depth is x + 4.2

Andrew's depth is x + 4.2 + 16 or x + 11.8

1) andrew's depth = x + 11.8, where x is 15.8.

What is m∠AED?<br><br><br><br> Enter your answer in the box.<br><br> °
Vladimir [108]

Answer:

<AED = 65

Step-by-step explanation:

1. Find the value of "x"

Remember, verticle angles are congruent. A verticle angle is formed when two lines intersect, the verticle angles are the angles that are opposite from eachother.

This means that;

<AEB = <CED

Substitue int he values;

5x - 10 = 3x + 40

Inverse operations;

5x - 10 = 3x + 40

-3x         -3x

2x - 10 = 40

    +10     + 10

2x = 50

/2    /2

x = 25

2. Find the measure of <AEB

Subsitute in the value for "x" that was found;

<AEB = 5x - 10

5 (25) - 10

125 - 10

115

3. Find the measure of <AED

Use a linear pair, a linear pair is two angles whose sum is 180 degrees. If one can put two angles together, and they form a straight line, then it is a linear pair.

<AEB and <AED are make a linear pair because together they form line BD.

This means that;

<AEB + <AED = 180

Substitute in the values;

115 + <AED = 180

<AED = 65

Choose the simplified form of  the fifth term of 6C4(2x)2(-y2)4.​
Katarina [22]

You didn't give us the choices.   It doesn't matter.  I think you're trying to write

\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4

= \dfrac{6!}{4! 2!} ( 4x^2 y^8)

= \dfrac{6(5)}{2} ( 4x^2 y^8)

=60x^2 y^8

Answer: 60 x² y⁸
