Answer:
you spent $72.21 in total
Step-by-step explanation:
The mathematical expression in this case is
(x+3)/2
Answer:
The domain in interval notation is [-4,∝) or set build: {x|x
Step-by-step explanation:
I'm assuming the 9x and the 36 are in the root
first we must solve for x
substract 36 to both sides
divide by 9 to both sides
simplify left side
simplfy right side
The domain in interval notation is [-4,∝) or set build: {x|x-4}
Answer:
Step-by-step explanation:
4) C looks pretty good
5) D looks great
:) ask if you'd like to know how I figured that out
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
