Answer:

Step-by-step explanation:

The one that looks most closely to this.

(3b + 2r) + (4b + r) Remove the brackets.

3b + 2r + 4b + r Rewrite so the terms are close to each other.

3b + 4b + 2r + r Combine

7b + 3r or

3r + 7b

One of the two of these can be given as an answer. Please give choices if you want me to give an exact answer.

$\implies {\blue {\boxed {\boxed {\purple {\sf { \: 7b + 3r}}}}}}$

$\sf \bf {\boxed {\mathbb {Step-by-step\:explanation:}}}$

$\: (3b + 2r) + (4b + r)$

➼ $\: 3b + 2r + 4b + r$

Combining like terms, we have

➼ $\: 3b + 4b + 2r + r$

➼ $\: 7b + 3r$

Given that P = (-5, 5) and Q = (-13, 10), find the component form and magnitude of 2 vector PQ.

Brut [27]

Define unit vectors along the x-axis and the y-axis as $\hat{i} , \, \hat{j}$ respectively.

Then the vector from P to Q is
$\vec{PQ} = (-13+5)\hat{i} + (10-5)\hat{j} = -8\hat{i} + 5\hat{j}$
In component form, the vector PQ is (-8,5).

The magnitude of vector PQ is
√[(-8)² + 5²] = √(89) = 9.434

Answer:
The vector PQ is (-8, 5) and its magnitude is √89 (or 9.434).
