=4n - 1
Since the sequence is add 4 and 3-4 = -1
20 x 4n = 80-1 = 79
49, because if he bought 9 you need to add that to 40 to get the whole
J = 506
J needs to be isolated so add 263 to both sides. -263 is cancelled out and 263 + 243 is 506.
Hence the answer of 506
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.
what is b? from the first equation in the system, y + 2 = b.
