HELP PLEASE !!!!!!! Pythagorean theorem

Mathematics
1 answer:
Phoenix [80]4 years ago
4 0

Answer:

\large\boxed{x=8\sqrt3}

Step-by-step explanation:

The Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have:

leg=8, leg=x,\ hypotenuse=16

Substitute:

8^2+x^2=16^2

64+x^2=256        <em>subtract 64 from both sides</em>

x^2=192\to x=\sqrt{192}\\\\x=\sqrt{(64)(3)}\\\\x=\sqrt{64}\cdot\sqrt3\\\\x=8\sqrt3

Answer:

-7 + 8 m + 4 n thus A. is your Answer

Step-by-step explanation:

Expand the following:

-(-8 m - 4 n + 7)

-(7 - 8 m - 4 n) = -7 - -8 m - -4 n:

-7 - -8 m - -4 n

-(-8) = 8:

-7 + 8 m - -4 n

-(-4) = 4:

Answer:  -7 + 8 m + 4 n

An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with a sum of 160. Show your wo
Andrew [12]
Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.

Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.

Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7 

Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18

Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.

Answer: 37,39,41,43

The circumference of a circle can be found by multiplying Pi by the diameter. True False
Softa [21]
Here's a formula to find the circumference of a circle
c = 2 × π × r

Multiplication has commutative property, we can change the order of operands without changing the result. I move 2 to the right.
c = π × 2 × r

Remember d = 2 × r
c = π × d

The answer is true. The circumference of a circle can be found by multiplying pi by the diameter
