What is the surface area of the pyramid

its 165 i think

Step-by-step explanation: Surface are is the complete are of a shape when its in its template mode or 2d mode.  the length of the radius of each triangle is 7 multiply that times 5 would give you 35. Multiply 35 times 4 gives you the area of the 4 triangles. Now the middle is 5 times 5 length times width; this would give you 25 add that and your total should be 165

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
