Answer:
it is 81 with doing some simple math
Answer:
D
Step-by-step explanation:
a perfect square trinomial is
factorized is
so as you can see option A and B can't be, because they have -49y^2 and it has to be plus
so the other options are C and D
in the trinomial a=4 and b=\pm 7
the roots of a^2 and b^2
so it's option d with b=-7
1) Solve one of the equations for either variable.
2) Substitute the expression from Step 1 into the other equation.
3) Solve the resulting equation.
4) Substitute the solution in Step 3 into one of the original equations to find the other variable.
5) Write the solution as an ordered pair.
Answer:
AB = 150 degrees
Step-by-step explanation:
Right triangle has a 90 degree angle. One angle is 30 degrees. There is 180 degrees in one triangle. 180-30= 150.
