Please answer for area <3 thank you! (:

9x+36

Step-by-step explanation:

With the given equation Area=1/2(Base*Height), all you need to do here is plug in base and height. The height here can be either side, since you're finding the area of a right triangle, but let's use 18 as the height. If 18 is the height, then x+4 is the length.

Plugging these into the equation gives us:

Area=1/2(18(x+4)

Area=9(x+4)

Area=9x+36

Step-by-step explanation:

1/2 x( 18 x X+4)

That simplified would be like 9 x ((x/2)+2)

Or I'm just over thinking and it's the 1st thing I said ""-w-

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
