Answer:

10x^2 + 8x

Step-by-step explanation:

Area of the outer rectangle = 5x(3x + 2) = 15x^2 + 10x

Area of the inner rectangle = x(5x - 2) = 5x^2 - 2x

Area of the shaded region = (15x^2 + 10x) - (5x^2 - 2x)

= 10x^2 + 8x

5x(3x + 2) - x(5x - 2) required expression.

Step-by-step explanation:

I get there are 2 rectangles in figure.

How can I get the area of shaded region? What if, I subtract the area of inner rectangle from outer rectangle. Ya It will surely work (⌒o⌒).

Now,

Area of outer rectangle = \sf length \times  breadth

5x \times (3x + 2)

5x(3x + 2)

Again,

Area of inner rectangle = \sf length \times  breadth

=x \times (5x - 2)

=x(5x - 2)

\sf Area \:of \:Shaded\: region = \: Area_{\:outer}-Area_{\:inner}

\sf \: 5x(3x + 2) - x(5x - 2)

If We simplify further then,

= 15x² + 10x - 5x² + 2x

= 10x² + 12x

Area of shaded region is 10x² + 12x in a simple way.

Solve for x. -1+14x 12+17
tino4ka555 [31]

Answer:

x=9

Step-by-step explanation:

These two angles are equal since they are alternate exterior angles

-1 +14x = 12x+17

Subtract 12x from each side

-1 +14x-12x = 12x-12x+17

-1+2x= 17

Add 1  to each side

-1+1+2x = 17+1

2x = 18

2x/2 = 18/2

x =9

Two airplanes start at the same place and travel in opposite directions,one at 395 miles per hour and the other at 422 miles per
Hitman42 [59]

plane 1 travels 395 miles in 1 hour

plane 2 travels 422 miles in 1 hour

together, they travel (395+422) 817 miles in 1 hour

to have 2451 miles between then, they'd need to travel

\frac{2451 miles}{817 miles}=3

so in 3 hours, they'll be 2451 miles apart
