4xplus 5 5y equals -10

Step-by-step explanation:

4x+5 5y=-10

4x +5+5y= -10

bring the 4x and 5y together and take +5 to the other side

4x +5y= -10-5

4x + 5y= - 15

you can't go further in simplifying it

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
