If you would like to solve the equation x^2 + 12 * x = -11, you can calculate this using the following steps:
x^2 + 12 * x = -11
<span>x^2 + 12 * x + 11 = 0
</span>(x + 1) * (x + 11) = 0
1. x = - 1
2. x = - 11
The correct result would be x = - 1, or x = - 11.
Answer to your question:
D = d < -6
Using the Pythagorean theorem:
6^2 + X^2 = 14^2
36 + x^2 = 196
X^2 = 196-36
x^2 = 160
x = SQRT(160)
x = 4 SQRT(10)
Or as a decimal:
x = 12.65 inches
Answer:
[x-h]^2 + [y-k]^2 =r^2
Step-by-step explanation:
Let x and y be an arbitrary point along the circle
The equation of the circle is given as:
[x-h]^2 + [y-k]^2 =r^2
Answer:
a ratio is a comparison of two numbers or measurements
the objects being compared are called the terms of the ratio.
if the tow terms are different units this is called a rate.
example:
David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?
solution:
Distance covered by David in 1 hour is
= 600 / 8
= 75 miles per hour
Distance covered by John in 1 hour is
= 380 / 5
= 76 miles per hour
When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.
