X^2 - 3xy = (-7)^2 - 3(-7)(4)

= 49 + 84

= 133

Make sure you remember that (-7)^2 = (-7)(-7) = positive 49

What are the answers for 1-4 this is geometry.
elena-s [515]

Answer/Step-by-step explanation:

1. x*21 = 24*14 (intersecting chords theorem)

21x = 336

x = 336/21

x = 16

2. 27*x = 45² (secant-tangent rule)

27x = 2,025

x = 2,025/27

x = 75

3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)

5x + 25 = (10)*6

5x + 25 = 60

5x = 60 - 25

5x = 35

x = 35/5

x = 7

4. (4x + 2)*8 = (5x + 1)*7

32x + 16 = 35x + 7

Collect like terms

32x - 35x = -16 + 7

-3x = -9

x = -9/-3

x = 3

Find the distance between the points with coordinates (-26,0) and (95, 0).
mote1985 [20]

Answer:

0

Step-by-step explanation:

Distance between two points is the slope .

Slope =change in y/change in x

Given (-26,0) and (95,0)

x1 = -26

y1 = 0

x2 = 95

y2 = 0

Slope = y2 - y1 / x2 - x1

0-0/95-(-26)

0-0/95+26

0/121
