Answer:
-6u + 7
Step-by-Step Explanation:
Rearrange Terms:
(8 - u) - 1(5u + 1)
(-u + 8) - 1(5u + 1)
Distribute:
(-u + 8) - 1(5u + 1)
(-u + 8) - 5u - 1
Eliminate Redundant Parentheses:
(-u + 8) - 5u - 1
-u + 8 - 5u - 1
Subtract the Numbers:
-u + 8 - 5u - 1
-u + 7 - 5u
Combine Like Terms
-u + 7 - 5u
-6u + 7
Solution:
-6u + 7
Answer:
I believe it should be 32.9
Step-by-step explanation:
Answer:
n = 20.
Step-by-step explanation:
The external angles of a polygon add up to 360 degrees. So:
30 + 42 + 16(n - 2) = 360 where n is the number of sides of the polygon.
16n + 30 + 42 - 32 = 360
16n + 40 = 360
16n = 320
n = 20.
Answer:24
Step-by-step explanation:
the number of the right triangle is to subtract the number
Answer:
<h2>
The right option is twelve-fifths</h2>
Step-by-step explanation:
Given a right angle triangle ABC as shown in the diagram. If ∠BCA = 90°, the hypotenuse AB = 26, AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
The right option is therefore twelve-fifths
