3x+2y=10
12x+5y=25
Solve by substitution or elimination
1 answer:
3x + 2y = 10 ....multiply by -4
12x + 5y = 25
-------------------
-12x - 8y = -40 (result of multiplying by -4)
12x + 5y = 25
------------------add
-3y = - 15
y = -15/-3
y = 5
3x + 2y = 10
3x + 2(5) = 10
3x + 10 = 10
3x = 10 - 10
3x = 0
x = 0
solution is (0,5)

34^2 + 20^2 = 1156 + 400 = 1556
47^2 = 2209
because the squares of the 2 smaller sides is less than the square of the longer side the triangle is Obtuse
Answer:
( x - 5 )( x + 2 )
= x² + 2x - 5x - 10
= x² - 3x - 10
