Therefore: 9 + 15 + 36 = 50
Answer:
Step-by-step explanation:
They are equivalent. Use the distributive property.
3(x+3)
the 3 on the outside of the parenthesis is multiplied by the variable(the letter) and thenthe constant(number) inside the parenthesis.
makes and equivalent equation 3x+9
Here is how to solve it:
1) isolate x for x+y=2:
x=2-y
2)now plug this value in 3x^2-y^2=1
3(2-y)^2-y^2=1
simplify to get 2y^2-12y+11=0
and you get:
3)plug these(y1,y2) values in x+y=2
and you get:<span>
