Which expression is equal to 5^4 ⋅ 5^8? a). 5^12 b). 5^4 c). 5^2 d). 5^−4

It should be A. You would keep the 5, and the exponent should be 4+8, which is 12.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
