Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
I think that they all are because scientific notation is where if a number is too big to write down somebody will just wright it to the power of what the number is equal to.
The sum of this equation is 5
Answer:
Perimeter expression: 3x-3+3x+x+4
Area expression: ( (3x-3)*(x+4) ) / 2
X= 5
Step-by-step explanation:
Perimeter is all the sides added together.
Area is base times height divided by 2
If perimeter is equal to 36 set the perimeter equation to 36 and solve for x.
