Our answer is
Our greatest common factor, or GCF, is
, so when we factor is out, our divide each term by
, we get our answer. To check this, we can multiply the
back across the parenthesis and see if we get the same result as our initial question.
Hope this helped! :))
It's neither prime or composite.
1 only has a single factor which is 1, so you can't really say.
Answer:
x = 4√2
Step-by-step explanation:
<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>
To solve, we will follow the steps below:
using Pythagoras theorem
opposite² + adjacent² = hypotenuse²
14² + y² = 18²
196 + y² = 324
subtract 196 from both-side of the equation
196 -196 + y² = 324-196
y² =128
Take the square root of both-side
√y² = √128
y =√128
y = √64×2
y =√64×√2
y = 8√2
x = half of y
x = y/2
x = 8√2 ÷ 2
x = 4√2
Answer:
- A
Step-by-step explanation:
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
