Answer: s=12
Step-by-step explanation:
s(12-3)=108
12s-3s=108
9s=108
Divide both sides by 9
s=12
U use distribution property
They can only sit one way because they are still in a row
Or did you mean like how many different ways can they sit?
Answer:
about 11.5 cm.
Step-by-step explanation:
I know the measurement of the other leg is about 11.5 cm. I know because I used the Pythagorean theorem.
a^2+b^2=c^2.
"a" and "b" are the values of the legs of the triangle, while "c" is the measure of the hypotenuse. We know that 8cm is the measure of one of the legs, and 14 cm is a measure of the hypotenuse.
8^2+b^2=14^2 simplified: 64+b^2=196
Then, I subtracted 64 on both sides, so I would have "b" by itself.
b^2=132
Next, I found the square root of both b^2 and 132, so I would find the true value of "b."
b=11.4891252931
So, the measure of the other leg rounded to the nearest tenth is about 11.5.
2 to the negative 1 power. When you divide two exponents with the same base, you subtract the two exponents to get your answer.
