Answer: x=7.21
Step-by-step explanation: This is a right triangle- remember the Pythagorean theorem: a² + b² = c². To find leg a, you'd use a = √(c² - b²) **leg a would be the side that is labeled with 12. To find leg b, you'd use b = √(c² - a²) *this is the equation we need. To find the hypotenuse, or <em>c</em>, you'd use c = √(a² + b²). This equation works for right triangles only.
Hope this helps :)
B2-7b+12=0
(b-3)(b-4)=0
b= 3 or 4
Answer:
x=1
Step-by-step explanation:
3x+3=5+x

2x=2
x=1
Answer:
C: +3
Step-by-step explanation:
We know this because Royce added money to his bank account, not subtract (b). The other options are just there to confuse you.
I hope this helps!!
The six scores have to average out to the mean, so their sum has to be six times the mean. Since the sum of the first five is 5 more than 5 times the mean, the remaining score must be 5 less than the mean.
Answer: 5 points below the mean
