What is the measure of x?

Mathematics
1 answer:
UkoKoshka [18]3 years ago
7 0

Answer:

x=4

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+5) *x = 6^2

x^2 +5x = 36

Subtract 36 from each side

x^2 +5x - 36 = 0

Factor

( x-4) (x+9) = 0

Using the zero product property

x-4 = 0  x+9 =0

x = 4  x=-9

Cannot be negative since that is negative length

x=4

#3 the answer is 4.
The reasoning for this is because x=-1 so if it is applied where x is at you have to subtract instead of multiplying in this equation. So 2xsquared is 2-1 which is 1. Same thing for 6x (6-1) which is 5. So the problem would end up being 1-5 which equals 4.

15 feet of edging costs $24.98. How much will 28 yards cost?
GuDViN [60]

Answer:

  139.888 $

Step-by-step explanation:

Data :

   15 ft = 24.98$

   So

  1 yard = 3 ft

15ft / 3 ft = 5 yard

So  

   5 yard  = 24.98$

28 yd / 5yd = 5.6

    5.6 × 24.98 =  139.888
