Answer:
AB = 7.07 units
BC = 8.06 units
AC = 12.04 units
Step-by-step explanation:
To find the length for each side of the triangle, apply the distance formula between each pair of vertices.
<u>AB</u>
<u />
<u>BC</u>
<u />
<u>AC</u>
Step-by-step explanation:
A number that is negative is less than 0, so
So this function is negative, when x is less than -2
Answer to 12: C.
Explanation: By dividing 60 by 15 you get 4 and by dividing 32 by 8 you get 4. 15 and 8 both go into it evenly so that is the answer.
Answer to 14: B
Explanation: when you divide 236.25 by 7 you get 33.75 and then multiply that by 2 and you get 67.7 so you know 2 fluid ounces of milk contain 67.7 mg of calcium
sorry i couldnt answer 13
Hello from MrBillDoesMath!
Answer:
Solutions: x = +\- 5i or x = +\- sqrt(5)
Discussion:
Factor x^4 - 25:
x^4 - 25 = (x^2+5) (x^2-5) => factor x^2 - 5
x^4 - 25 = (x^2+5)(x + sqrt(5)) (x - sqrt(5)) => factor x^2 + 5
x^4 = 25 = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))
Hence the solutions are
x = +\- 5i and x = +\- sqrt(5)
Thank you,
MrB
