If you know that 84 is 70% of the whole, explain how you can use proportional reasoning to determine the whole. use the drop-down menus to explain your answer.

The value of whole is 120.

Step-by-step explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

So, we have use the proportion i.e. to determine the value of whole.

Hence, the value of whole is 120.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

the answer will be b x² +x-1

step-by-step explanation:
