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

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

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

Answer:

The first amount is larger by 25% or .25a

Step-by-step explanation:

Lets increase a by 50%

The increase is .5a

So the new value is a + .5a = 1.5a

Now we will decrease the new value by 50%

decrease = .5 (1.5a) = .75a

The new value of a is 1.5a - .75a = .75a

a > .75a

a - .75a = .25a

a is bigger than .75a by .25a
