Solve x2 - 8x = 3 by completing the square. which is the solution set
[4 - 19,4 + /19}
{4 - v11, 4 + /11)
{4 - v8, 4 + }
[4 - v3, 4 + (3)

4\pm\sqrt{19}

Step-by-step explanation:

Move everything to left side

Now to solve this square equation we need to find Descriminant

As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
