If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answers
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

Create an equation to solve for x using the trapezoid midsegment formula:
Answers
Answer:
Equation for x: 3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = [tex]\frac{CD + FE}{2}[/tex]
3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
solve using substitution
y = -x - 6
4x - 2 =0

have a good day/night
Answer: 63.25 (Decimal) or 63 1/4 (fraction)
Step-by-step explanation: 64 - 3/4. 3/4 is 0.75 in decimal form, so subtracting it would be 63.25 which would be 63 1/4 in fraction form. I don’t think you can simplify it since 1/4 is already at it’s smallest form.

(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!
Answers
Answer:
(60-5.8) ÷ 5 - 3² = 1.84 (approx)
Step-by-step explanation:
(60-5.8) ÷ 5 - 3²
First simplify the numbers inside the bracket.
(60-5.8) = 54.2
Now, the equation is in the form of,
54.2 ÷ 5 - 9
Put 54.2 ÷ 5 in a bracket for easy calculation.
(54.2 ÷ 5) - 9
Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84
Subtract 9 from 10.84
10.84 - 9
You will now get the answer as,
1.84 (approx)
