Slope of line perpendicular to ax+by=c is b/a
given
-2x-8y=18
slope of perpendicular is -8/-2=4
y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b
y=4x-15
Tis communitive property.
Okeh bye
Answer:

Step-by-step explanation:
step 1
Find the surface area of the cube
The surface area of the cube is equal to

where
b is the length side of the cube
w have

substitute

step 2
Find the lateral height of the square pyramid
we know that
the surface area of the square pyramid is equal to

where
B is the area of the base
b is the base of the lateral triangle (base of the square)
h is the lateral height of the square pyramid

-----> is the same surface that the cube

substitute the values and solve for h
