Answer:
49
Step-by-step explanation:
Put the variable values in place of the corresponding variables, and do the arithmetic.
x² +3(x +y) =
5² +3(5 +3) = 25 +3(8) = 25 +24 = 49
-15d - 12 = -4(d + 3) - 11d
-15d - 12 = -4d - 12 - 11d
-15d - 12 = -15d - 12
+12 +12
--------------------------------------------
-15d = -15d
---------------------------------------------
All real numbers are the solution.
3rd one for sure I also just took a test on this
