Hi there
I am glad to help you
6x² + 7x - 5 = 0
In this case, you need to factor the left side of the equation
(3x + 5)(2x - 1) = 0
Now set factor equal to zero (0)
3x + 5= 0 or 2x - 1 = 0
x = -5/3 or x = 1/2
I hope that's help, if you don't understand please let me know !
If P is a midpoint of DE, then:
DP + PE = DE and DP = PE → 2DP = DE
We have:
DP = 3x + 2 and DE = 10x - 12
Substitute:
2(3x + 2) = 10x - 12 |use distributive property
(2)(3x) + (2)(2) = 10x - 12
6x + 4 = 10x - 12 |subtract 4 from both sides
6x = 10x - 16 |subtract 10x from both sides
-4x = -16 |divide both sides by (-4)
x = 4
Substitute the value of x to the equation DP = 3x + 2:
|DP = 3(4) + 2 = 12 + 2 = 14
Answer: DP = 14 units
