Answer:

3x^4 +7x^2 -20

Step-by-step explanation:

To find how tall the building is, multiply how high each story is by the number of stories

height = (x^2+4) * (3x^2-5)

FOIL

first x^2 *3x^2 = 3x^4

outer -5x^2

inner 4*3x^2 = 12x^2

last -5*4 = -20

Add them together

3x^4 -5x^2 +12x^2 -20

3x^4 +7x^2 -20

Answer:

1/(5^12 * 32^3 * 9^15)

Step-by-step explanation:

5^-12 = 1/(5^12)

32^-3 = 1/(32^3)

9^-15 = 1/(9^15)

1/(5^12) * 1/(32^3) * 1/(9^15) = 1/(5^12 * 32^3 * 9^15)

Easy question so yall get can get brainliest by answering correctly first
storchak [24]

Answer:

Answer:

Distance is 13.6 units.  

Which means it is 13

Step-by-step explanation:

Given a grid shows the positions of subway stop and house. The subway stop is located at (-7, 8) and house is located at (6, 4).

we have to find the distance between house and the subway stop.

Points are (-7, 8) and (6, 4).

Using distance formula,

D= /(x2-x1)^2+(y2-y1)^2} = (6-(-7))^2+(4-8)^2=(13)^2+16}={169+16}={185}=13.60147\sim13.6units.

Hence, distance between house and the subway stop is 13.6 units.
