Which of the following has one solution? Select all that apply. A) 10×+5=3(5×+7)
B) 5×-10=×+20
C) 2(6+×)=14+2×
D) 2(4+×)=8+2×

Step-by-step explanation:

(A). 10x + 5 = 3(5x + 7)

x  = - 16

(B). 5x - 10 = x + 20

x = 7.5

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
