Answer:
I know the joke your trying to pull of :>
Step-by-step explanation:
But if u really need help it's 19
2x + 6y = 5
x + 3y = 2 .....multiply by -2
-----------------
2x + 6y = 5
-2x - 6y = - 4 ...(result of multiplying by -2)
----------------add
0 = 1 (incorrect).......no solutions because the lines are parallel.
little tip :
if ur system of equations comes out where it is not equal....like 4 = 5, or 6 = 7...then there is no solutions.
if ur system of equations comes out where it is equal...like 5 = 5 or 8 = 8, then there is infinite solutions
if ur system of equations comes out where a variable = a number....like x = 2 or y = 5.....then there is one solution
Answer:
22cm²
Step-by-step explanation:
For the area of triangle,
base = 2 + 2 + 2 = 6cm
height = 4cm
Area = 1/2 x base x height
= 1/2 x 6 x 4
= 12cm²
For area of the rectangle,
length = 5cm
breadth = 2cm
Area = length x breadth
= 5 x 2
= 10cm²
Area of compound shape = 12 + 10 = 22 cm²
Flip the bottom part after the "/" so you get ((x+3)/9)*(6/(x+12)) Cancel and multiply to get 2(x+3)/3(x+12) this is as simplified as it is going to get.
