X^2 +6x-6=0 taking -6 to cross the equal sign
x^2+6x=6 by completing squ.
x^2 +6x+ 9= 6+9
x^2 +6x +9 =15
(x+3)^2= 15
x+3= 15^0.5
x= 3,87298-3 or -3.87298-3
x= 0.87298 or -6.87298
Steps to solve:
k + 10 = 27
~Subtract 10 to both sides
k = 17
Best of Luck!

Hello, recall that you need to write complete questions in order to get exact answers. Here we have a missing diagram so I can help you in a general way. A prism is a three dimensional shape that has two identical ends (flat faces
) and the same cross section all along its length. A cube is a special type of prism having six identical square sides. So the volume of a prism given the length of a side as s is:

For example, suppose we have a box formed by unit cubes as indicated in the figure below, so the length of one side of the blue box will be:

So the volume of the blue box is:

C.) A <span>dilation with a scale factor of 4, with center of dilation at the origin
Here, You can either draw the figure or compare the coordinates,
B = (4, 4) then B' = (1, 1)
C = (-4, 4) then C' = (-1, 1)
D = (-4, -4) then D' = (-1, -1)
E = (4, -4) then E' = (1, -1)
So, Every coordinate is reducing by 4th factor... Hence, dilation factor is 4 about the origin
