y = 20 + 2.5x
have to write more or I cant post this
Answer:
4(3x+y)^2
Step-by-step explanation:
36x^2+24xy+4y^2
=9*4x^2+6*4xy+4y^2
=4(9x^2+6xy+y^2)
=4(3x+y)*(3x+y)
=4(3x+y)^2
Algebraic expression means Letter Can stand for numbers. Ex: 2y+5 and Y=10
-3x-2(5x-7)=-12
-3x-10x+14=-12
-12-14=-26
-3x-10x= -13x
So -13x=-26
x= 2
