Use Pythagoras theorem

Two triangles are similar

(6+3)*12/2 - 6*8 /2 = 30
Answer:
x=1
Step-by-step explanation:
6-3x=5x-10x+8=
move all terms to the left:
6-3x-(5x-10x+8)=0
add all the numbers together, and all the variables
-3x-(-5x+8)+6=0
get rid of parentheses
-3x+5x-8+6=0
add all the numbers together, and all the variables
2x-2=0
move all terms containing x to the left, all other terms to the right
2x=2
x=2/2
x=1
Answer:
y = 5x+3
Step-by-step explanation:
a general line is represented by the equation:
y = mx + n
a line with m=5, that goes through (-1,-2), should satisfy the equation:
-2 = 5×(-1) + n
this is because any point on the line, satisfies it's equation.
from this we get n = 3, hence our answer
