Explanation:

Your different answers came about as a result of an error you made in the Pythagorean theorem calculation.

√(100 +100) = √200 = 14.142 . . . . same as vector calculation

Greeley [361]

Answer: $\boxed{Sol=\{\dfrac{7}{4} \}}\\$

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

$(x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\$

the sum of three numbers is 15. the second number is double the first. the third number is 5 less than the first. what are the t

tigry1 [53]

Hello from MrBillDoesMath!

Answer:

5, 10, 0

Discussion:

Let "f" be the first number. Then the questions tells us that

f + 2f + (f-5) = 15 =>

f + 2f + f - 5 = 15 => add 5 to both sides

4f = 5+ 15 = 20 => divide both sides by 4

f = 20/4 = 5

The numbers as

f: 5

2f: 10

(f-5): 0

Thank you,
