$3\ consecutive\ even\ numbers:\ 2x,2x+2,2x+4\\\\2x(2x+2)+40=(2x+4)^2\\\\
4x^2+4x+40=4x^2+16x+16\\\\
4x^2-4x^2+4x-16x=16-40\\\\-12x=-24\ \ |:(-12)\\\\x=\frac{24}{12}=2\\\\2x=2=4\\\\2x+2=6\\\\2x+4=8\\\\Numbers\ are\ 4,6,8.$

Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4

sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

$y\propto (x+2)^2$

When x=8 and y=250

We have to find the value of y when x=4

$y=k(x+2)^2$

Where k= Proportionality constant

Substitute the values

$250=k(8+2)^2$

$250=100k$

$k=\frac{250}{100}$

$k=5/2$

Now, substitute x=4 and k=5/2

Then, we get

$y=\frac{5}{2}(4+2)^2$

$y=\frac{5}{2}\times 36$

$y=90$
