Answer:
solution = (1.-2)
Step-by-step explanation:
put x= 1 and y = -2 in this system : y=-4x+2 and y + 2x = 0
you have : - 2 = - 4(1)+2 and -2 +2(1)=0
-2=-2 and 0=0 .....right
Volume is a three-dimensional scalar quantity. The volume of the composite figure is 14 ft³.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the composite figure is,
Volume = (1/3 ×1.5 × 2 × 2) + (2 × 1.5 × 4)
= 2 ft³ + 12 ft³
= 14 ft³
Hence, the volume of the composite figure is 14 ft³.
