Answer:
we can't see please zoom in.
Step-by-step explanation:
Ok so remember
order of simplification
PEMDAS
parenthaseese
exponents
multiplicaton or division whichever comes first
addition or subtraction whichever comes first
ok so remmeber work from the left to right parenthasees first and work from inside to outer parenthasees
so first one
innermost parenthasees first so
first step is 2-4
subtract 4 from 2
second one
if xy=0 then assume x and y=0 so
(a+2)(b-9)=0
a+2=0
a=-2
b-9=0
b=9
so answe ris a=-2
b=9
third questions
innermost parenthaees first
subtract 4 from 2
ok
1. subtrac 4 from 2
2. a=-2, b=9
3. subtract 4 from 2
Part A: C part B: C. I hope this helps
Answer:
9
inches
or
12.728 inches
Step-by-step explanation:
Use Phytagorean Theorem
Since both all sides of a square are equal, this means that 
and 
are equal.
So that leaves us with:
Simplify
Divide both sides by 2
Simplify
Find the square root of both sides
a = 9
(or if you want the decimal, rounded to the 3rd decimal place: 12.728)
Answer:
The answer is 72 inches in 24 hours.
Step-by-step explanation:
If 3 inches tall per hour, and you need to find the amount of rain in 24 hours, you just need to multiply the number of inches per hour by the number of hours required (24 hours):
3×24=72 inches
