Answer:The perimeter (length around the entire outside) is twice the length plus twice the width.
Step-by-step explanation: P = 2(L) + 2(W) = 2(12) + 2(10) = 24 + 20 = 44 The perimeter is 44 feet.
Answer:
y=3
Step-by-step explanation:
Answer:
-1/2x
Step-by-step explanation:
-1/2x represents the slope because it shows that the line is going down 1/2 every x. 1/4 would be where the line started or the y-intercept.
Answer:- A) U= { keys on a keyboard}
Explanation:-
- A set is a well defined collection of objects.
- A Universal set is the set containing all objects and all other sets are subsets of the universal set. It is denoted by 'U'.
Given set : S = {x,y,4,9,?}
Clearly it contains numbers (4,9), alphabets(x,y) and punctuation mark(?).
Thus the universal set of the given set must contain all of them.
Thus U={keys on a keyboard}
Step-by-step explanation:
remember that x^-n means 1/(x^n).
x^a × x^b = x^(a+b)
x^a / x^b = x^(a-b)
(x^a)^b = x^(a×b)
(x×y)^n = x^n × y^n
so,
a^2 / a^-2 = a^(2 - -2) = a^4
and
b^-3 / b^2 = b^(-3 - 2) = b^-5 = 1/(b^5)
that means we have then :
(a^4 × b^-5)^2 = (a^4)^2 × (b^-5)^2 = a^8 × b^-10 =
= a^8 / b^10 = a⁸/b¹⁰
