Find the length of x
zaharov [31]

Answer:

The answer is 2

Step-by-step explanation:

The hypotenuses of the triangles are different. One is 4 and the other is 5.

Lets use ratios to find the relationship of the hypotenuse and the base.

2.5:5

Turn this into a fraction

2.5/5

Now divide

2.5/5 = 0.5

The base of the triangle is half the length of the hypotenuse.

So 4 is x’s hypotenuse so:

4 x 0.5 = 2

X = 2

Distributive property pls helpp
GaryK [48]

9514 1404 393

Answer:

  • 4
  • 16

Step-by-step explanation:

If you consider matched parentheses to identify the contents of a "bag", the multiplier outside parentheses tells you how many bags you have. When you use the distributive property, you effectively dump all those bags on the table.

Here, the expression 4(6v +4) tells you there are 4 bags and each one contains 6v and 4. When you open them all up, you have ...

  4(6v +4) = 6v +6v +6v +6v +4 +4 +4 +4

Of course, we can use multiplication to simplify repeated addition, so we can also write this as ...

  4(6v +4) = 4·6v +4·4 = 24v +16

The numbers that go in your boxes are identified by their bold font style.

Using the Pythagorean theorem you can use:
