Answer:
s = u/tv
Step-by-step explanation:
To make s the subject of the formula in the equation of; u = tsv
,just divide both sides by (tv)...in which on the right hand side...it will cancel out t and v,hence leaving only s and then only the left hand side..it will give you your answer;
; u = tsv
; u/tv = tsv/tv
; s = u/tv
Answer:
x = 1.47 or x = -7.47
Step-by-step explanation:
x²+6x+9=20
This is a quadratic equation
x²+6x+9-20=0
x²+6x-11=0
Step 1 : Write the quadratic formula
x = <u>-b±√b²-4(a)(c)</u>
2a
Step 2 : Substitute values in the formula
a = 1
b = 6
c = -11
x = <u>-6±√6²-4(1)(-11)</u>
2(1)
x = <u>-6±√80</u>
2
x = -3 + 2√5 or x = -3 - 2√5
x = 1.47 or x = -7.47
!!
It's a equilateral triangle with each side being equal to the radius.
So the area is
