Cant seem to figure out the total surface area

189

Step-by-step explanation:

2bs+b^2

2x7x10+7^2=189

hopes it helps

189

Equation for surface area is 2bs +b squared ( b is base and a is side)

Step-by-step explanation:

2bs+b squared

2 * 7 * 10=140

B squared = 7 squared which is 49

140 + 49=189.

Hope it helped.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

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.
