(w^2+5w) + (2w^2 +w +7)
when adding or subtracting polynomials, just combine the like terms from each set:
w^2 + 2w^2 = 3w^2
5w +w = 6w
so you would have : 3w^2 + 6w + 7
Answer:
[−7,−5)∩[−5,0] = [-5]
Step-by-step explanation:
A = A1 ∩ A2 means that A contains the intersected elements (shared elements) of A1 and A2
Your answer is A, that $56 + (-$2) + (-$3)
Answer:
67 degrees
Step-by-step explanation:
If angle a is 113 degrees, angle d will be 113 degrees subtracted from 180 degrees. Because angles in a straight line adds up to 180 degrees.
The length is 12, because if it's 9 inches wide it has two sides of 9 inches which is 18. Then subtract that from the intial value 42 to get 24. After, you divide 24 by 2 due to there being 2 sides of the box and 24 is the sum of both sides. Hopethis helps!
