Set up a ratio between the small triangle and the large one.
AD/ AE = AC / AB
(8 + 2)/8 = 10 / x
10/8 = 10/x Cross multiply
10x= 80 Divide by 10
x = 8
Answer 4th one down. <<<<====
Initial of those two points? its always the leftmost one, or whichever has the lowest x value
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
Answer:
Step-by-step explanation:
If you would like to find the x-intercepts of the function f(x) = - 2 * x^2 - 3 * x + 20, you can calculate this using the following steps:
f(x) = - 2 * x^2 - 3 * x + 20
f(x) = - (2x - 5) * (x + 4)
1. x = - 4
2. x = 5/2
(x, y) = (-4, 0)
The correct result would be (-4, 0).
1 should be 21 because u have to add m(1)+112+57 and get 180°,,,, angle 2 should be 33 because there is a right angle (90°) and when u add 90+57=147 u gotta substract it from 180 and u get 33,,, angle 3 is 71 because there is another right angle (90°) and when u add 19 and 90 it’s 109 and substract from 180 and u get 71
