Answer:
10.9 feet
Step-by-step explanation:
12^2 = 5^2+h^2
144 = 25 + h^2
-25 -25
h^2 = 119
h = square root 119
h = 10.9 ft
Answer:
feet further.
Step-by-step explanation:
Since these are mixed numbers that are both in fourths, we can easily subtract the two numbers. However, I find it easier if we first convert both mixed numbers into improper fractions.
Now we can subtract the numerators:
simplifies down to 
.
Converting to a mixed number is easy - 2 goes into 9 4 times (8) with one remainder so:
.

X^2 +6x-6=0 taking -6 to cross the equal sign
x^2+6x=6 by completing squ.
x^2 +6x+ 9= 6+9
x^2 +6x +9 =15
(x+3)^2= 15
x+3= 15^0.5
x= 3,87298-3 or -3.87298-3
x= 0.87298 or -6.87298
Answer: x=12
Step-by-step explanation:
1/3 x -4
1/3x=4 <---- First add 4 to each side of the equation (moves the "-4")
1/3x(3)=4(3) <---- Muliply each side by "3" to get rid of the fraction
x=12
