2 x (multiplication sign, not an x) (x+7) or 2(x+7)
Answer:
150
Step-by-step explanation:
15 times 8 = 120
14-8 = 6
6 times 5 = 30
150
Answer:
Step-by-step explanation:
Start by drawing out the triangle on the graph:
(See picture)
(By the drawing you can judge me that I am a really bad artist)
Theta and the side lengths are labeled, the hypotenuse has a length of √21 by Pythagora's theorem. Now, time to put everything to the trigonometric functions:
(Suppose that x is theta as I can't type it)
By some basic understanding that's all that I can do.
X^2-10x-24=0
(x+2)(x-12)=0
x=-2 or x=12
