I’m really stuck on this problem. explain the work!
4y-70=12y+2
: )

y = -9

Step-by-step explanation:

4y - 70 = 12y + 2

Add 70 to both sides

4y - 70 + 70 = 12y + 2 + 70

simplify

4y = 12y + 72

subtact 12y from both sides

4y - 12y = 12y + 72 - 12y

simplify

-8y = 72

divide both sides by -8

-8y divided by -8 = 72 divided by -8

solve

y = -9

5050

hope this !

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
