Answer:

y=-2

Step-by-step explanation:

3y+2=-2+y

subtract the 1y from both sides leaving you with 2y+2=-2

Then subtract 2 from both sides leaving you with 2y=-4

Then divide by 2 on both sides leaving you with y=-2

For problems 3 and 4, find the missing side of the triangle. Leave answers in simplest radical form.

maria [59]

Answer: 3. 4 $\sqrt{13}$ 4. $\sqrt{225}$

Step-by-step explanation:

8^2 + 12^3 = c^2

64 + 144 = c^2

208 = c^2

√208

$4\sqrt{13}$

The final answer is the square root of 208

8^2 + b^2 = 17^2

64 + b^2 = 289

-64 64

b^2 = 225

$\sqrt{225}$
