Answer:
3b+b and 2(2b)
Step-by-step explanation:
if the original value of x was negative then X the opposite sign version of X would have to be positive Princeton's if I start with x equals -3 then x equals -3 equals + 3 which is positive
D.3.1 is the greatest value from the list.
Answer:
WV should be equal to XY
Step-by-step explanation:
since it is the HL postulate meaning hypotenuse and leg, we need to show that the hypotenuses of both triangles are equal since we are already given that one of their legs are congruent. we are also given that they are right triangles.
Answer:
x=√139-3, x=-√139-3
Step-by-step explanation:
to complete the square, you first move the constant to the other side of the equation-its already done for you!
now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.
What you do to one side has to be done with the other.
x^2+6x+9=130+9
now you can factor the square:
(x+3)^2=139
squareroot both sides:
x+3=√139
x+3=-√139
now subtract both sides by 3
x=√139-3
x=-√139-3
