Answer:
-25
Step-by-step explanation:
i got -25. i just used a calculator
9^ ? 3^2 + 7^2
81 ? 9 + 49
81 > 58
c^ > a^2 + b^2
answer is obtuse triangle
Solid is if x is greater/less than or equal to (there isn’t a symbol for it) the line and the line would be dashed if x is < or > something
x² + 7x - 4 = 0
a = 1, b = 7, c = -4
x = [-b +/- √(b² - 4ac)]/2a
= [-7 +/- √(49 + 4)]/2
= (-7 +/- √53)/2
