-y=-8x+4
y=8x-4
5x+3(8x-4)=17
5x+24x-12=17
29x-12=17
29x=29
x=1
8(1)-y=4
-y=-4

Answer:
-960
Step-by-step explanation:
5+43=48
3-23=-20
48*-20=-960
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
