Answer:
x = -3/2 ± i(√11)/2
Step-by-step explanation:
The quadratic formula can be used directly, but I find it convenient to divide by 14 first:
x^2 +3x +5 = 0
The solution to ...
ax^2 +bx +c = 0
is given by the formula ...
x = (-b ±√(b^2 -4ac))/(2a)
Here, we have a=1, b=3, c=5, so the formula gives the solutions ...
x = (-3 ±√(3^2 -4·1·5))/(2·1) = -3/2 ± i(√11)/2 . . . . . solutions are complex
300,000
the hundred thousands place is "2" and 28 is closer to 30
Answer:
4/5 divided by 9/10
4/5 times 10/9
=8/9
Step-by-step explanation:
hope this help you good luck
You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504
Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.
