Combine like terms: 3p2q2-3p2q3+4p2q3-3p2q2+pq PLEASE HELP!!! ASAP!!!
ch4aika [34]

Answer:

p²q³ + pq and pq(pq² + 1)

Step-by-step explanation:

Given

3p²q² - 3p²q³ +4p²q³ -3p²q² + pq

Required

Collect like terms

We start by rewriting the expression

3p²q² - 3p²q³ +4p²q³ -3p²q² + pq

Collect like terms

3p²q² -3p²q² - 3p²q³ +4p²q³ + pq

Group like terms

(3p²q² -3p²q²) - (3p²q³ - 4p²q³ ) + pq

Perform arithmetic operations on like terms

(0) - (-p²q³) + pq

- (-p²q³) + pq

Open bracket

p²q³ + pq

The answer can be further simplified

Factorize p²q³ + pq

pq(pq² + 1)

Hence, 3p²q² - 3p²q³ +4p²q³ -3p²q² + pq is equivalent to p²q³ + pq and pq(pq² + 1)

Hi there! :)

a) (ii) The two angles are vertical angles, so they are congruent.

b)(i) y = 71°

  (ii) The two angles are alternate interior angles, so they are congruent.

c) z = 44°

(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.

b) (i)

∠y is an alternate interior angle, therefore:

m∠y = 71°

c) Use the sum of interior angles of a triangle to determine the measure of angle z:

180 = 65 + 71 + z

180 = 136 + z

180 - 136 = z

z = 44°.
