Answer:

If the solutions (or roots, or zeros) are -4 and -8 then the factors are (x+4) and (x-8), so the equation would by:

Y=(x+4)(x-8) foil it out.

Y=x(2)+4x-(8)x-6)

Y=x(2)+(5/2)x-6

Hope this helped.

Which expression is equivalent to 5(4x+3) - 2x

Troyanec [42]

Good evening

Answer:

18x + 15
3(6x + 5)

Step-by-step explanation:

Unfortunately you didn’t provide the expressions to chose from ,however we can get other expressions From this one like this:

5(4x+3) - 2x = 20x + 15 - 2x

= (20x - 2x) + 15

= 18x + 15

we can also write 18x + 15 = 3×(6x) + 3×(5x) = 3(6x + 5)

then

these two expressions :

18x + 15
3(6x + 5)

are equivalent to 5(4x+3) - 2x

A postal carrier can

ioda

Answer: 6 hours or 360 minutes

Step-by-step explanation:

First find out how long it takes to deliver to one house.

Convert hours to minutes.

2.5 x 60 = 150 minutes total

Divide to find the time per house

150 minutes / 130 houses = 1.15 minutes per house

Now multiply this rate by the number of houses (312).

312 x 1.15 = 360 minutes

If you want it in hours then divide by 60.

360/60 = 6 hours.
