Y=x^2, y=x+12 solve by substitution method

y=x^2

y=x+12

x^2=x+12

x=-3

x=4

y=-3+12

y=4+12

y=9

y=16

(x1,y1)=(-3,9)

(x2,y2)=(4,16)

Step-by-step explanation:

Hope this helps!

can i have brainliest please

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.
