Answer:
4√7
Step-by-step explanation:
5√7 + √7 - 2√7
Taking out common term, √7.

Simplify the terms in the bracket.
= √7 (4)
= 4 √7
7 times, means 7 x intercepts, means 7th degree
answer is 7th degree
Simplifying
30c + -45d
Factor out the Greatest Common Factor (GCF), '15'.
15(2c + -3d)
Final result:
15(2c + -3d)
