Answer:

n^2 +14n +49

Step-by-step explanation:

(n+7)^2

(n+7) (n+7)

FOIL

first = n*n

outer = n*7

inner = 7*n

last 7*7 =49

Add them together

n^2 +7n+7n+49

Combine like terms

n^2 +14n +49

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).

Dvinal [7]

Step-by-step explanation:

Hey there!

The coordinates of a triangle are;

A (1,2)
B (1,-2)
C (-2,-2)
Scale factor = -4 and centre at (0,0)

Now, We have;

P(x,y)----------- P'(kx, ky)

Keep formula;

A(1,2)---------- A'(-4×1 ,-4×2)

= A'(-4, -8)

B(1,-2)------------- B'(-4,8)

C(-2,-2)-------------C'(8,8)

[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Hope it helps..

A light private plane can fly 120 mph in still air. Flying against the wind, the plane can fly 320 miles in the same time it req

Debora [2.8K]

Alright, lets get started.

A light private plane can fly 120 mph in still air.

Suppose the speed of wind = x mph

Against the wind, speed of plane will be = 120-x

With the wind, speed of plane will be = 120+x

Flying against the wind, the plane can fly 320 miles, so time taken will be

t = $\frac{320}{120-x}$

With the wind, the plane can fly 640 miles, so time taken will be

$t = \frac{640}{120+x}$

Both times are given same, so

$\frac{320}{120-x}= \frac{640}{120+x}$

Cross multiplying

$320(120+x) = 640(120-x)$

Dividing from 320

$120+x = 2(120-x)$

$120+x = 240-2x$

$3x = 120$

x = 40 mph

So, the speed of the wind is 40 mph. : Answer

Hope it will help :)
