Answer:
r=1
Step-by-step explanation:
3(2x-2)-r+3x=2(7x+1)-5x-9
6x-6-r+3x=14x+2-5x-9
9x-6-r=19x-7
-6-r=10x-7
-r=10-1
-r=9
-r/-1=9/-1
r/9=-9/9
r=1
Answer:
Expand
2b + 3 = 2 -3b -9
Correct like terms
2b + 3 = 3b - 7
Move 2b to the otherside as a negative number and -7 to the otherside positive number.
-4 = -5b
Divide both sides by negative five
b is equal to 4/5

A
Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2 → A
