So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6
Step-by-step explanation:
17. 2(a+3b)-3(4a+b)
2a+6b-12a-3b
2a-12a+6b-3b
-10a+3b
correct answer is B.-10a+3b
18. simplify (,3a³-7a²+a)+(-6a³+4a²+8)
3a³-6a³-7a²+4a²+8+a
-3a³-3a³+a+8
correct answer is D. -3a³-3a³+a+8
10.8 m it was crawling 1.2 m every minute, so since it crawled for 9 minutes, you would just multiply the two numbers
Answer:
<h2>2x</h2>
Step-by-step explanation:
<h3>x × 1 + x1 = ?</h3><h3>1x + 1x = ?</h3><h3>2x</h3><h3 />
You will have to use trig to solve this:
The side you have is adjacent to the known angle
The side you are looking for is opposite the known angle
^^^This means you need to use tan:
tan(24) =
.445222 =
^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x
5.3 ≈ x
Hope this helped!
