Answer:
315
Step-by-step explanation:
7/4 of 180°
= 1.75 * 180
= 315°
7x^2+x+9 - (<span>3x^2+4x-5)
= </span>7x^2 + x + 9 - 3x^2 - 4x + 5
= 4x^2 - 3x + 14
Answer:
<h2 /><h2>-7 , -1</h2>
Step-by-step explanation:
if the equation of line p is
4x+7y=20 then the equation of line q must be
-7 x +4y=15 because perpendicular lines have
slopes with a product of -1
