In the 5/4 = ?/12 .. you have to solve if 4 goes into 12 that is 3. 4•3 equals 12. Now you have to multiply 5•3 and it will fill in your blank space. I hope this Helps.

In the top of the bird, you can see that the denominator was multiplied by 2. And whatever you do to the top, you have to do to the bottom. And whatever you do to the bottom, you have to do to the top. So multiply the numerator by 2 also. 4 x 2 = 8 so the answer is 8/2.

For the tail of the bird, you can see that it went from 8 to 56. Well what times 8 equals 56? 7. So it multiples the fraction by 7. So you want to multiply the 1 by 7 too. So you get the answer is 7/56.

You just repeat the same process on the other fractions. (:
If you need help with a specific fraction, just let me know! I'd be glad to help!

Answer:

$4(x^{2} -4)^{2} -76$

Step-by-step explanation:

Take out 4:

4(x^2-8x)-12

=4(x^2-8x+16-16)-12

=4(x^2-8x+16)-64-12

=4(x^2-4)^2 - 76

= $4(x^{2} -4)^{2} -76$

How do you solve it?

Elis [28]

At heart we're being asked for a line through two points,

$(40^\circ \textrm{ C}, 355 \textrm { m/s}) \quad \textrm{and} \quad (49^\circ \textrm{ C}, 360 \textrm { m/s})$

In general the line through (a,b) and (c,d) is

$(y-b)(c-a)=(x-a)(d-b)$

Check that you understand why both (a,b) and (c,d) are on this line.

Here our indepedent variable, instead of x, is T, temperature. Our dependent variable is v, velocity. Substituting,

$(v - 355)(49 - 40) = (T - 40)(360 - 355)$

$9(v - 355) = 5(T - 40)$

$v-355 = \frac 5 9 T - \frac{200}{9}$

$v= \frac 5 9 T - \frac{200}{9} + 355$

$v= \frac 5 9 T + \frac{2995}{9}$

That's our answer; let's check it.

When T=40, v = (5/9)40 + (2995/9) = 355 good

When T=49, v= (5/9)49 + (2995/9) = 360 good

Quadrilateral LMNO is similar to quadrilateral PQRS. Find the measure of side QR.

dalvyx [7]

Answer:

The measure of the side $QR$ is 8.8.

Step-by-step explanation:

Since $LMNO \sim PQRS$ , then $SP \propto OL$ , $RS \propto ON$ , $RQ \propto MN$ and $QP \propto LM$ . From figure we have the following relationship:
