Answer:
x = ±√10i (i outside the radical), or approximately ±3.62i, or no solution depending on your class.
Step-by-step explanation:
x^2 + 10 = 0
x^2 = -10
x = ±√-10
x = ±√10i (i outside the radical), or approximately ±3.62i.
The solution is not real.
If you meant x^2 - 10 = 0 then x = ±√10 or approximately ±3.62. This solution is real.
Answer:
6.2
Step-by-step explanation:
3^2+2^2=c^2
9+4=c^2
13=c^2
=c
5^2+^2=x^2
25+13=x^2
38=x^2
=x
6.2=x
Answer:
6 cups of sugar
Step-by-step explanation:
If you need 12 cups of sugar for every 16 cups of cranberries, for 4 cups of cranberries you'll need 6 cups of sugar.
Here's the working:
12 cups of sugar = 16 cups of cranberries
4 cups of cranberries is 1/2 the amount of 16 cups of cranberries so we have to divide by 1/2
12 cups of sugar ÷ 2 = 6 cups of sugar
Answer:
x = 48 degrees
Step-by-step explanation:
=> x = 180-132 (angles on a straight line add up to 180 degrees so we'll subtract the other angle from 180 to get x)
=> x = 48 degrees
