1 answer:

5 0

There are 5280 feet in a mile
45 * 5280 = 237600
there are 3600 seconds in an hour (60 minutes time 60 seconds)
so we have 237600 feet in 3600 seconds
237600 / 3600 = 66 feet per second.

a triangle on a coordinate plane has a vertices of (2,6),( -4,-4), and (0,-6). The triangle is dilated with a scale factor of 2.

frosja888 [35]

To solve this problem you have to multiply all of the coordinates by 2

So your answers are

(2,6) ---> (4,12)

(-4,-4) ---> (-8,-8)

(0,-6) ---> (0,-12)

Could you please make brainly :)

Hope this helps ;)

Factor completely 2x^2 − 2x − 40.

zubka84 [21]

Step-by-step explanation:

Hey there!

Given;

$= 2 {x}^{2} - 2x - 40$

Solve it by using mid-term factorization.

$= 2 {x}^{2} - 2x - 40$

$= 2 {x}^{2} - (10 - 8)x - 40$

$= 2 {x}^{2} - 10x + 8x - 40$

Take common and simplify them to get answer.

$2x(x - 5) + 8(x - 5)$

$= (2x + 8)(x - 5)$

$= 2(x + 4)(x - 5)$

Therefore the answer is option D.

Hope it helps..

Can you guys help me with This one please too

grigory [225]

Ok so
each buss costs b price
2 busses so 2b=buss price
20 is tip PER DRIVER, so times 2 because 2 busses so 2 drivers (40)
total is 240 max

tip+busscost=240
40+2b=240
hmm, that's not an option

we can undistribute the 2
2(20+b)=240
move around
2(b+20)=240

answer is third one
