Complete the square
move the 3 aside and work in parenthasees
f(x)=(x^2+6x)+3
take 1/2 of 6 and square it (6/2=3, 3^2=9)
add 9 and -9 inside
f(x)=(x^2+6x+9-9)+3
factor perfect square
f(x)=((x+3)^2-9)+3
get rid of parenthases
f(x)=(x+3)^2-9+3
f(x)=(x+3)^2-6

2nd choice

The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +
prisoha [69]

Let

x------>  the first even integer

x+2---->the second even integer

x+3---->the third even integer

we know that

x+(x+2)+(x+4)=36 -----> equation that represent the situation

solve for x

Combine like terms in the left side

(x+x+x)+(2+4)=36

3x+6=36

therefore

<u>the answer is the option B</u>

3x+6=36

In parallelogram HIJK, the measure of angle H is 45 degrees. 1.Find the measure of J and explain how you know
s2008m [1.1K]

Answer:

45°

Step-by-step explanation:

A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral).

For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).

Consecutive angles are supplementary that is ∠A + ∠B = 180°.

The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.

In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:

∠H = ∠J (opposite angles of a parallelogram are equal)

∠J = 45°
