Answer:
(2, -7).
Step-by-step explanation:
x + y = -5
x - y = 9 Adding, to eliminate y:
2x = 4
x = 2
Plug this into first equation:
2 + y = -5
y = -5 - 2
y = -7.
now onto the second one,
now, the extraneous part, I don't see either as extraneous, 3 and 12 do work, however, I take it is referring to the root, so if we nevermind the root has ± versions, and say only assuming the value coming from the root is say positive, then
Answer:

and added them all up
Answer:
10.5 cm^2
Step-by-step explanation:
Area of a triangle = 1/2(L x H)
Reading from the diagram
length = 7 cm
height = 3 cm
therefore
Area of the triangle = 1/2( 7×3)
Area = 10.5 cm^2
