What is the factored form of 5x-625x^4

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.
