Answer:
A
Step-by-step explanation:
x² - 4x - 5 = 0
x² - 5x + x - 5 = 0
x(x - 5) + (x -5) = 0
(x - 5)(x + 1) = 0
x - 5 = 0 ; x + 1 = 0
x = 5 ; x = -1
Answer:
15(2) + x(2)= perimeter

Step-by-step explanation:
Using the rule of radicals
×
⇔ 
Given
(3 +
)(2 +
)
Each term in the second factor is multiplied by each term in the first factor, that is
3(2 +
) +
(2 +
) ← distribute both parenthesis
= 6 + 3
+ 2
+ 
Answer:
its the second one.
Step-by-step explanation:
When x=0 y=50 when y=0 x=+\-5. -x^2 makes the parabola open downward y(x)=2x^2+50;y(3)=2*9+50=32
