Step-by-step explanation:
6-2w²+4w
6-2w(w+2)
Answer:
P(A) = at most 25 of them like to swim
P(B) = at least 26 of them like to swim
P(A) +P(B) = 100%
=> P(B) = 100-P(A) = 100-38 =62%
=> B is correct
The three inside angles of a triangle need to equal 180 degrees.
In a right triangle one of the angles is 90 degrees.
This means the other two angles need to equal 180-90 90 degrees.
You are given one of the angles of 52 degrees, so subtract that from 90 to find the third angle.
90 - 52 = 38 degrees.
The answer is A.

Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42
