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

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

olasank [31]

Answer:

C. $cA-cB=c(A-B)$

Step-by-step explanation:

Given that A and B are matrices and $c$ is a scalar, then the distributive property of scalar multiplication over addition is given by;

$c(A+B)=cA+cB$

The distributive property of scalar multiplication over subtraction is

$c(A-B)=cA-cB$

The correct answer is C.
