PLEASSSEEE ELXPLAIN THE ANSWER I REALLY NEED HELP ON THIS

Answer:

It will take him <u>20 days</u> to read a 300-page book.

Step-by-step explanation:

Given:

Stephen read a 90-page book in 6 days.

If he continues reading at that rate.

Now, to find the time it will take him to read a 300-page book.

So, we solve using unitary method:

If, Stephen read 90 pages in 6 days.

So, Stephen read 1 page in = $\frac{6}{90}$ days.

Thus, Stephen read 300 page in = $\frac{6}{90} \times 300$

$=\frac{1800}{90}$

$=20\ days.$

Therefore, it will take him 20 days to read a 300-page book.

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

ss7ja [257]

Answer:

Step-by-step explanation:

y=2(x-8)(x+2)

The x intercepts occur when y=0, so when x=8 and -2

The vertex is where the equation is at a minimum/maximum in this case (x,y)=(3,-50)

The axis of symmetry occurs between the two roots, 8 and -2 which x=3

The y intercept is the value of y when x=0, in this case (0, -32)

Solve for h. A=1/2h(b+B)

Ulleksa [173]

A = 1/2h(b + B)
2A = h(b + B)
h = 2A/(b + B)
