Answer:

9

Step-by-step explanation:

area of the triangle makes the area of this triangle be 18 cause half base x height=18 equals area for the full triangle, however if you want to find shaded part you must find the area of the non shaded triangle wich is 1.5x6=9 so subtract 9 from 18 and you get 9 wich is the area of shaded part

Answer:

9

Step-by-step explanation:

area of a triangle = ( base length × height ) / 2

given base length = 3ft and height = 6ft

so area = ( 3 × 6 ) / 2

==> multiply 3 and 6

area = (18)/2

==> divide 18 by 2

area = 9ft²

Which of the following is an equivalent equation obtained by completing the square of the expression below? x^2+6x−8=0 A (x+3)^2

valentina_108 [34]

Answer:

Solving the equation $x^2+6x-8=0$ by completing the square method we get $\mathbf{(x+3)^2=17}$

Option B is correct option.

Step-by-step explanation:

We need to solve the equation $x^2+6x-8=0$ by completing the square method.

For completing the square method: we need to follow: $a^2+2ab+b^2=(a+b)^2$

We are given:

$x^2+6x-8=0$

Solving by completing the square

$x^2+2(x)(?)+(?)^2-8=0$

We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.

So, adding and subtracting (3)^2

$x^2+2(x)(3)+(3)^2-8-(3)^2=0\\(x+3)^2-8-9=0\\(x+3)^2-17=0\\(x+3)^2=17$

So, solving the equation $x^2+6x-8=0$ by completing the square method we get $\mathbf{(x+3)^2=17}$

Option B is correct option.
