Answer:
660
Step-by-step explanation:
ok this one is a little more tricky
20*5=100 do not double this one
20*12=240 do not double this one
20*13=260 do not double this one
remember the area of a triangle is A=1/2l*w
plug in the values
A=1/2(5)(12)
A=30 you have to double this one because there is two of them
60
now you must add up all your values
100+240+260+60=660
i hope i am not wrong... but hope it helps!

Step-by-step explanation:
-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1

Answer:
x - intercept(s) : ( -9, 0 )
y - intercept(s) : ( 0, 54 )
