2. The hundredths model is shaded to represent a division problem

Which equation is represented by the model?
In order to receive full credit on this question label the model showing
what the parts represent
A 0.72 99
B 0.72 90.09
C 0.72.98
D. 0.72.9 0.08

Option D

Step-by-step explanation:

If the whole grid is considered to be 1,

Each small grid will value =

There are 72 shaded grids which represent the hundreds = 0.72

When these grids have been divided into 9 equal rows, number of grids in each row = 8

And the value of 8 grids in each row = 0.01 × 8 = 0.08

So the equation is,

0.72 ÷ 9 = 0.08

Therefore, equation represented by the model will be Option (D).

you can't solve x because it is 2 linear equation and you only have one equation

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
