Answer:
4√7
Step-by-step explanation:
5√7 + √7 - 2√7
Taking out common term, √7.
= √7 ( 5 + 1 - 2)
Simplify the terms in the bracket.
= √7 (4)
= 4 √7
THe area of the whole circle is pi r^2 = 6^2 * pi = 36pi
There are 360 degrees in a crcle so this sectors area i (30/360) *36pi
= 3 pi
Step-by-step explanation:
6x + 2 = y --------1
3y - 18x = 12 -----2
From 1
substitute y = 6x +2 in equation 2
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12
Therefore, no solution!
