sin = y / r

sin = -60 / 61

y = -60

r = 61

x = ?

---To find x, we'll use the Pythagorean theorem.

60^2 + x^2 = 61^2

3600 + x^2 = 3721

x^2 = 121

x = 11

Quadrant 3 is (-, -) = x and y coordinates are both negative.

Therefore, x = -11.

cos = x / r

x = -11

r = 61

cos = -11 / 61

Hope this helps!

3^x ( x^2 -3) i don't know how to solve this problem
geniusboy [140]
3ˣ (x² - 3)

Basically, just multiply everything together.

Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.

Step 2 : 3x ˣ × (-3) = -9ˣ

Now, our new question is : 3x³ - 9x

You wouldn't simplify this because x³ is NOT the same as x.

~Hope I helped!~

I need help :) please if you know this I would appreciate it if you can help me
elena-14-01-66 [18.8K]

Step-by-step explanation:

a.

2(3x) - 5x = 4

6x - 5x = 4

x = 4

B. -5(x-4)+8x=29

-5x+20+8x=29

3x+20=29

3x=9

x=3

C. 2y=18+2(3-y)

2y=18+6-2y

2y=24-2y

4y=24

y=6

D. c = -b - 11

3c + 6 = 6b

3( -b - 11) +6 = 6b

-3b-33+6=6b

-3b-27=6b

-27=9b

3=b
