Answer:
x = 10; WX = 5; HJ = 10
Step-by-step explanation:
The hash marks indicate that points W and X are midpoints of their respective segments. That makes WX a midline of the triangle. The midline is always half the length of the base (HJ). We can use this fact to write an equation relating the lengths.
HJ = 2·WX
x = 2(x -5) . . . .substitute the given expressions
x = 2x -10 . . . . eliminate parentheses
10 = x . . . . . . . add 10-x to both sides
This value of x tells you that ...
HJ = x = 10
WX = x -5 = 5
The answer is 19/8 and in the decimal form it's 2.375
1) That equation cannot be factored. And you cannot find roots by using the root theorem or any exact method.
2) That means that you should use either a numerical method, which exceeds the high school level (even the basics college levels), or a graphing calculator.
3) I opted for the graphing calculator and found these roots for you:
One important observation is that the degree of polynomila, i.e. 6, indicate the maximum number of roots:
So, you can expect 6 solutions. These are:
Real roots:
x ≈ 0.65
x ≈ 2.13
Complex roots:
x ≈ -1.48 - 0.24i
x ≈ - 1.48 + 0.24i
x ≈ 0.59 - 1.87i
x ≈ 0.59 + 1.87i
Answer:
Sanchez applied 1,800 fluid ounces of herbicide to his 300 acres of corn.
Step-by-step explanation:
Let's identify what we already know:
1) Sanchez has 300 acres of corn
2) For every 1 acre, Sanchez applies 6 fluid ounces of an herbicide.
So, we need to figure out how many fluid ounces Sanchez used for the entire six acres. We can create a formula for this:
300 acres x 6 fluid ounces = x
x equals total number of fluid ounces. We multiple the number of acres by the fluid ounces, to get 1,800 fluid ounces for the entire 300 acres of corn.
Conclusion! Hope this helps!
