Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
Answer:
4
Step-by-step explanation:
64 divided by 16 is 4.
To check your answer, you can always add the top: 20+4 which is 24, and multiply that by 16: which is 384-the total number of seats.

Answer:
Step-by-step explanation:
I believe it is 26?
your equation is:
a² + b² = c²
So, plug in what you know.
5² + 12² = c²
5² means 5*5, so your "a" is equal to 25
12² means 12*12, so your "b" is equal to 144
25 + 144 = c²
to this part, add a and b. you'll get 169.
169 = c²
next, use your calculator and square both sides.
√169 = √c²(you don't really have to do anything with the c, just get rid of the ²)
squaring both sides will get rid of the ² in c, and will give you your new number:
c = 13
