If you would like to know the value of 'c' in the quadratic equation, you can find this using the following steps:

3x^2 + 5x + 7 = 0

ax^2 + bx + c = 0<span>
a = 3
b = 5
c = 7

The correct result would be 7.</span>

Why is - t - 3 written as 3 - t? Is it wrong if it is left as -t -3?
Eddi Din [679]

-t-3 and 3-t are not the same since t-3 would result in a negative answer since both -t and -3 are negative. While in t-3 t is positive and -3 is negative. it is wrong if its left as t-3 since -t-3=3-t is false.

1)
you have similar triangles(ABC, ADE), so their side length ratios are equal

8/2=4/CE
CE*4=4
CE=1


2)
angle bisector theorem:
CD/DA=BC/BA

CD/DA=10/8
I:AD=10CD/8

we also know AC=AD+CD=6
II:CD=6-AD

insert II in I:

AD=10(6-AD)/8
=5(6-AD)/4
=(30-5AD)/4
4AD=30-5AD
9AD=30
3AD=10
AD=10/3
