Answer:
-6x+12
-9+5a
7x+63
8y-4/5x-12
Step-by-step explanation:
To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.
-3(2x)-3(-4) All I did here was expand the problem to show what i mean by terms.
-6x+12
Do this for each problem.
0.1(-90)+0.1(50a)
-9+5a
-7(-x)-7(-9) For this one you are taking negatives times negatives so each answer will be positive.
7x+63
4/5(10y)+4/5(-x)+4/5(-15)
8y-4/5x-12
Step-by-step explanation: The <em>intersection</em> of two figures can
be defined as the set of points that is contained in both figures.
In this figure, lines <em>h</em> and <em>i</em> intersect at C or we can
say that C is the intersection of lines <em>h </em>and <em>i</em>.
In this figure, C is the intersection of lines <em>h</em> and <em>i</em>
because C is the point contained by both <em>h</em> and <em>i</em>.
My friends your answer is
C) 27.00 sq ft

I think its number 5, sorry if im wrong
Answer:
8 cm
Step-by-step explanation:
Because A=a*a
Area equals length times length
So, 8 is the length
64 divided by some number must equal the exact same number. Let me show what I am talking about.
Our length is a. We multiply a times itself (because that's the formula for the square's area)
Does this number exist?
Yes, it does.
And it's a whole number.
And we know from our times tables that 8*8=64
Hope it helped you
