It would be 28 because you have to divide 112 into 4, because the picture is a square(most likely) so its sides are all equal

A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a

so 4 sqrt 7 is the length of each side

Answer:

7/24

Step-by-step explanation:

you have to have a common denominator so you multiply one denominator to the opposite numerator and denominator and vice versa. So for 2/3 you should get 16/24 and for 3/8 you should get 9/24. Then you subtract 9 from 16 and get 7. So the answer is 7/24

Write the Equation of the line in slope intercept form<br> (0, -3), (7.5,0)

makkiz [27]

Answer:

Step-by-step explanation:

First, start off by solving for the slope using this formula:

$\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$

Then, plug in the values: $\frac{0-(-3)}{7.5-0}$

Solve the equation: $\frac{3}{7.5}$

That's your slope.

Then plug in one of the coordinates given in the problem for x and y and solve this equation:

y= $\frac{3}{7.5}$ x+b

Hope that helped!!! :)

How to graph this problem ?

Doesn't it become like a reflection? For example instead of (3,1) it'll be (-3,-1) ?
