You said . . . -12√12 - 2√3 .
Before we get all tangled up trying to work on the whole thing at once,
take a look at that first square root: √12 .
That's the same thing as √(4 · 3) and you can break it up like this:
√(4 · 3) = √4 · √3 .
Now, we know what √4 is . . . it's just 2 .
So we can write the first half of your original big quantity like this:
-12 √12
= -12 · 2 · √3
= -24√3 .
NOW, finally, let's go back and rewrite the whole thing:
-24√3 - 2√3 .
Isn't that a lot nicer looking ?
It's nearly solved all by itself ... if you don't let the √3 scare you.
It just says -24(cows) - 2(cows) .
and everybody knows, that's just -26(cows).
So -24√3 - 2√3 is just -26√3 . (choice-C)
Answer:
Roasted Steak RS=14.47
Grilled Salmon GS= 25.21
Step-by-step explanation:
It's a 2 equation system as follows
E1-> 17RS+14GS=598.95
E2-> 28RS+7GS=581.64
We assume the system has only one solution and apply the following calculation to create a single equation
E3 -> 2x E2 -E1
That way the only incognit will be RS
(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95
39RS= 564,33
We solve for RS and then use E1 to solve for GS and E2 to check the answers
i dont know the answer, but i reccommend using mathpapa.com as they give you the answer PLUS the explaination.
Answer: Trigonometry is a branch of math that studies the relationship between the sides and the angles of triangles. Widely used in architecture, engineering, and many sciences, trigonometry is one of the most valuable branches of mathematics.
