Answer:
If the 2 numbers are the same, it will be zero. If the positive number is larger than the negative number, the sum will be positive. If the negative number is larger than the positive number, then the sum will be a negative number.
Step-by-step explanation:
Hi!!
Okay, the discriminant is -36, and using the quadratic equation, it should be
-1 +/- 3<em>i</em>
Answer:
13,600
Step-by-step explanation:
(h = 7, l = 6, w = 2) 10
70, 60, 20
2(h × w) + 2(h × l) + 2(w × l)
= 2(70 × 20) + 2(70 × 60) + 2(20 × 60)
= 2(1400) + 2(4200) + 2(1200)
= 2800 + 8400 + 2400
= 13,600
Divide by 2
Y = 2x - 2.5
x intercept: when y = 0
0 = 2x - 2.5
2.5 = 2x, x = 1.25
y intercept: when x = 0
Y = 2(0) - 2.5, y = -2.5
Solution: (1.25, 0) and (0, -2.5)
