Answer:

>180° (more than 180°)

Step-by-step explanation:

Angles are classified as ...

acute: < 90°
right: = 90°
obtuse: > 90°
straight/linear: = 180°
reflex: > 180°

It seems that we're looking at definitions:

obtuse : >90° :: reflex : >180°

Answer:

$P+Q=5x^2+4$

$Q-P=-x^2-4x+16$

Step-by-step explanation:

We are given

$P=3x^2+2x-6$

$Q=2x^2-2x+10$

Calculation of P+Q:

$P+Q=3x^2+2x-6+2x^2-2x+10$

now, we can combine like terms

$P+Q=3x^2+2x^2+2x-2x+10-6$

$P+Q=5x^2+0+4$

$P+Q=5x^2+4$

Calculation of Q-P:

$Q-P=2x^2-2x+10-(3x^2+2x-6)$

Firstly, we will distribute negative sign

$Q-P=2x^2-2x+10-3x^2-2x+6$

now, we can combine like terms

$Q-P=2x^2-3x^2-2x-2x+6+10$

$Q-P=-x^2-4x+16$

Vertex form of y=-4x^2+4x-6

AlexFokin [52]

Answer:

Step-by-step explanation:

y = -4x^2 + 4x + 6

Factor out the leading coefficient:

y = -4(x^2 - x) + 6

Complete the square:

y = -4(x^2 - x + (½)^2) + 4(½)^2 + 6

= -4(x-½)^2 + 7
