0 = x + 2 + x^2
x^2 + x + 2 = 0
a = 1, b = 1, c = 2
discriminant = b^2 - 4ac = 1^2 - (4 x 1 x 2) = 1 - 8 = -7
Answer:
2
Step-by-step explanation:
Answer:
b = 69/2 mm
Step-by-step explanation:
Let h: height of triangle
Let b: base length
Writing the height in terms of the base length: h = 2b + 5 mm
We equate that to the given height: 74 mm = h = 2b + 5 mm.
Solving this for b, we subtract 5 mm from both sides, obtaining
69 mm = 2b.
Then b = 69/2 mm

Answer:
1)2205little cherries
2)0.5.
Step-by-step explanation:
1)7little=2big

2)²/5x=¹/10what is the value of 10x-2
first find the value of x that is ¹/10÷²/5=¼
so x is ¼
insert the value ie 10×¼-2
=2.5-2
=0.5
