Answer:

1641.74 or 1641.74x^2

Step-by-step explanation:

if those x is an actual x then the answer is the second choice, if its for multiplication then its the first choice.

you have to multiply whats outside of the parenthesis first then multiply that number with -19.09

8.6x10x19.09 would equal to 86x19.09 which would equal to 1641.74

Answer:

3/10

Step-by-step explanation:

Numbers Given are:

1 1/2, 2 1/2, 1 2/3, and 2 5/6

The result at the end of all the math is 2 5/6.

1 2/3 + 2 5/6 = 4 1/2

Divide 4 1/2 by 1 2/3 to get 2 7/10.

Subtract 2 2/3 from 2 7/10 to get 1/5.

Multiply 1/5 by 1 1/2 to get 3/10.

So the number they thought of was 3/10.

Having a $75 added cost to the total price, we can presume they will never equal. It is easy to see if you make it algebraic:

$m=months\\t=total\\\\ProviderA => t = 39.95m\\ProviderB => t = 39.95m+75$

They will never equal each other.

Find the number to add to x^2-18x

pentagon [3]

Answer:

A. add 81; $(x-9)^2$

Step-by-step explanation:

The perfect square formula

$(a-b)^2=a^2-2ab+b^2$

Rewrite expression $x^2-18x$ as follows:

$x^2-2\cdot 9\cdot x$

So, to form a perfect square, $+9^2$ is missed.

When we add $9^2=81,$ we will get

$x^2-2\cdot 9\cdot x+9^2=(x-9)^2$
