Answer:

<20,23>

Step-by-step explanation:

2v = 2<0,-1> = <0,-2>

5u = 5<4,5> = <20,25>

2v + 5u = <0,-2> + <20,25>

= <20,23>

Answer:

<20,23>

Step-by-step explanation:

u= <4,5> and v= <0,-1>

2v = 2*<0,-1> = <0,-2>

5u = 5* <4,5> = <20,25>

2v+5u = <0,-2> + <20,25>

= <20,23>

Solve for b2: A=1/2h(b1+b2)

balandron [24]

Answer:

Step-by-step explanation:

$A = \frac{1}{2}h(b_{1} + b_{2})$

First let's multiply both sides by 2 to remove the $\frac{1}{2}$ fraction:

$2A = h(b_{1} + b_{2})$

Next, let's divide both sides by $h$ :

$\frac{2A}{h} = b_{1} + b_{2}$

Finally, let's subtract $b_{1}$ from both sides:

$b_{2} = \frac{2A}{h} - b_{1}$
