Whatsthe value of the expression 3[s3-6s] +4t2 when s=5 and t =3

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Two triangles can be formed with the given information. use the law of sines to solve the triangles. b = 49°, a = 16, b = 14
