Line up the equations and add them up, adding the x's together then y's (which should cancel out) then the totals.
Then the equation should equal -9x=36 and when tou solve x= -4.
Plug -4 in for x in one of the equations, I chose the second one, and solve.
y = -21
Hope this helps! :)
Answer:
4. 30 inches
5. 76.2 cm
6. 1024 sqaure inches
Step-by-step explanation:
4. √900 = 30 (area of a square = s²)
5. 30*2.54 = 76.2 cm
6. Each side is 2 inches longer ⇒ 30+2 = 32 inches (each side length)
area of a square = s²
32² = 1024 square inches

Answer:
Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.
