Hi there!

Work out the parenthesis.

Combine like terms.

Subtract 9 from both sides.

Subtract 4x from both sides

Divide both sides by -9
Formula is y = mx + b
Answer y = - 2/3x - 3
Answer:-26
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
side Ac is the opposite of angle B, therefore use the sin ratio to find ac since the hypotenuse is also given
sin B=opposite/hypotenuse
sin 27=ac/15
ac=sin27×15
=6.81
I hope this helps
