Answer:
11x
Step-by-step explanation:
Answer:
X = 3 x − 14
y = − x + 5
Step-by-step explanation:
Solve for the first variable, then substitute the result into the other equation.
(x-h)^2+(y-k)^2=r^2
(x-0)^2+(y+2)^2=9^2
x^2+y^2+4+4y=81
x^2+y^2+4y-81+4=0
x^2+y^2+4y-77=0
Answer:
Makenzie is correct, 13.93 ≈c
Step-by-step explanation:
the sides with determined lengths (see image) are A (13) and B (5). C however is not determined.
the correct equation would be to solve for c.
13² + 5² = c²

c ≈ 13.93
Clara solved for b and not c, which is incorrect.
