Please help!! Which equations have exactly one solution? Choose all answers that apply: a. 12x+12=13x-12 b. -13x+12=13x+13 c. -13x+12=13x-13 d. 12x+12=13x+12

2nd one in the first row is correct

probability for j is 1/4

while

a is 1/6

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

for future students the answer is b
