This is not a polynomial equation unless one of those is squared. As it stands x=-.833. If you can tell me which is squared I can help solve the polynomial.
Ok, that is usually notated as x^3 to be clear. I'll solve it now.
x^3-13x-12=0
Then use factor theorum to solve x^3-13x-12/x+1 =0
So you get one solution of x+1=0
x=-1
Then you have x^2-x-12 now you complete the square.
Take half of the x-term coefficient and square it. Add this value to both sides. In this example we have:
The x-term coefficient = −1
The half of the x-term coefficient = −1/2
After squaring we have (−1/2)2=1/4
When we add 1/4 to both sides we have:
x2−x+1/4=12+1/4
STEP 3: Simplify right side
x2−x+1/4=49/4
STEP 4: Write the perfect square on the left.
<span>(x−1/2)2=<span>49/4
</span></span>
STEP 5: Take the square root of both sides.
x−1/2=±√49/4
STEP 6: Solve for x.
<span>x=1/2±</span>√49/4
that is,
<span>x1=−3</span>
<span>x2=4</span>
<span>and the one from before </span>
<span>x=-1</span>
Answer:
The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft
Step-by-step explanation:
Given;
two side of the triangle, 6 ft and 6 ft
let the third side of the triangle = x
Apply the rules of length of a triangle to determine the third side of the triangle.
Based on this rule: (6 - 6) < x < (6 + 6)
0 < x < 12 ft
Therefore, the length of the third side will be greater than 0 but less than 12 ft
The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft
Answer:
1 pound = 16 ounces
2 pounds = 32 ounces
Given:
Cost for 2 pounds of bananas = $1.28
Price per ounce = 1.28/32 [∵2 pounds = 32 ounces]
=$0.04
Hence the cost of bananas per ounce is $0.04
Hope it helped!
3/2. you but as y over x and subtract the y’s then the x’s so -2-4 over -1-3 = -6/-4= 3/2
