2r² − 28r + 38 = 0
2 (r² − 14r) = −38
2 (r² − 14r + 49) = −38 + 2(49)
2 (r − 7)² = 60
(r − 7)² = 30
the answer is 2(r-7)² =60
Quantity is two numbers multiplied together, judging by the context, the answer is D, insufficient information.
Choice a and b are just numbers.
$70/day because a week has seven days so 490 divided by 7 is 70
G(x)=4x^2-3x+7
g(3)=4(3)^2-3(3)+7
g(3)=34
