Answer:
420
Step-by-step explanation:
We can find the prime factors of each of the numbers first before finding their LCM.
12: <em>2</em> × 2 × <u>3</u>
30: <em>2</em> × <u>3</u> × 5
42: <em>2</em> × <u>3</u> × 7
To find the LCM, we need to see if they are any common prime factors between all three numbers. The common prime factors are <em>2</em> and <u>3</u>. Then, we multiply 2 and 3 with the remaining outstanding factors, which are 2, 5, and 7.
LCM: <em>2</em> × 2 × <u>3</u> × 5 × 7 = 420
Answer:
No solution
Step-by-step explanation:
When lines are parallel, they do not intersect and they do not have a solution.
Thank You
Hope it helps u
Answer:
x=12
Step-by-step explanation:
This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that 
where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, 
. Next, solve what is under the root to get, 
. Finally, square root 144 for the final answer b=12.
Okay, so I had to resort to the calculator since I couldn't figure out how to do it, anyway here.
(-0.08928571428) -this is the answer according to it id says take a few numbers and see what answer fits it the most but yeah, I didn't help much.
