= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:
= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14
In short, Your Answer would be: 15u³ + 8u² - 3u + 14
Hope this helps!
I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
Remember,
To subtract 2/3-1/2 you have to make them equivalent
2/3×2-1/2×3 = 4/6 - 3/6=
1/6
<u>ANSWER</u>
<u>EXPLANATION</u>
We want to solve the trigonometric equation;
, where 
.
Taking square root of both sides gives,
Since B is in the first quadrant, we proceed with;
, because the tangent ratio is positive in the first quadrant.
.
Correct to the nearest degree,
Answer:
7
Step-by-step explanation:
24^2+b^2=25^2
576+b^2=625
<u>-576</u> <u>-576</u>
b^2=49
√b=√49
b=7
