7x3=21. All multiplication is is repeated addition! Hope I helped!

To factor a number out of an expression means to divide each term of the expression by that number.

So, if you want to factor $a$ from the expression $x+y+z$ , you'll write it as

$a\left(\dfrac{x}{a}+\dfrac{y}{a}+\dfrac{z}{a}\right)$

So, in your case, when you divide both terms by -5 you get

$-10a \div (-5) = 2a,\quad -25\div (-5) = 5$

So, the expression becomes

$-10a-25 = -5(2a+5)$

Cost = .10 x ( n ) + 50
= .10(400) + 50
= 40 + 50
= 90

I hope this helps.
