Answer:
option A is correct
Step-by-step explanation:
Base=20m
Height=12h
We know that,
╭☞Area=1/2×20×12
╭☞1/2×240
╭☞240/2
╭☞120m^2
First we find the factors
a^3-8 is the differnce between 2 perfect cubes and is factored out to
(a-2)(a^2+2a+4)
the factors are (a-2) and (a^2+2a+4)
a^4+16
this is not factorable, unless you mistiped it and it was really a^4-16
the factor is 1
a^3+2a^2+4a
factor out the a
a(a^2+2a+4)
this is the most factored out form
the factors are (a) and (a^2+2a+4)
there are no common factors except 1 so 1 is the answer
Answer:
-w − z = <4, -7>
z − w = <6, 1>
w − z = <-6, -1>

Answer:

Step-by-step explanation:
You multiply it by itself 4 times, therefore being 18 to the power of 4
Answer:
2/5 = 4/10
4/10 = 40%
Explanation:
2/5 is a simplified fraction, and one of the bigger fractions it’s made by 4/10. Do you can use 4/10, but can also use 8/20, 20/50, 40/100, so on. Since we know that any fraction that of ten can be turned into a percentage easily (2/10=20%, 5/10=50%,9/10=%90), then 4/10 is equal to 40%. So 40% of the people in Jeremiah’s class are boys.
