Answer: ⇒ 7x+5y

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

6(x+y)+x-y

expand

6(x+y)=6x+6y

=6x+6y+x-y

simplify by equation

6x+6y+x-y=7x+5y

=7x+5y

Hope this helps!

Thanks!

Use the net as an aid to compute the surface area of the triangular prism.

Harrizon [31]

Answer:

Option C. $564\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles

$SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)$

$SA=60+364+140$

$SA=564\ mm^{2}$

Jane took a train traveling at an average speed of 60 mph from Boston, MA to Washington, D.C. The trip took 8 hours. On her way

Trava [24]

Answer:

6.4 minutes

Step-by-step explanation:

The question gave us the following details:

Average speed = 60mph

Time spent on trip = 8 hours

Average speed of express train on way back = 75mph

T = distance/speed

D = distance

V = speed

T = d/v

d = v(t)

d = 60 x 8

= 480

Such that

480/75

= 6.4 hours.

That is 6 hours 40 minutes is the length of time it would take on the trip home.

Thank you!
