Which solids have infinitely many planes of symmetry? check all that apply. right square pyramid cube right cylinder right hexagonal prism sphere

The answer is: Sphere and Right cylinder.

The explanation for this answer is shown below:

By definition, the numbers of planes of symmetry depends of each solid (a figure of three dimensions). The plane of symmetry divides the solid into two congruent halves which have mirror images.

Based on the information above, a cube has nine plane of symmetry, a square pyramid has four planes of symmetry, the hexagonals prims have thirteen and the spheres a cylinders have infinite number of plane of symmetry.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
