The total area would be the combined area of all three
Let’s knock out the first 2
4.5 * 13 = 58.5 * 2 = 117
Now the last
4.5 * 9 = 40.5
117 + 40.5 = 157.5 ft^2
The answer to 6 x (-8) = -48
<u>It is -48 because anytime you multiply one negative to one positive it will be negative if you multiply two negative's it come out to be a positive </u>
Hope this helps
Have a wonderful day
Answer:
9
Step-by-step explanation:
Let the unknown number be x
Sum means add
7 + 3x = 34
Subtract 7 from each side
7+3x-7 = 34-7
3x = 27
Divide by 3
3x/3 = 27/3
x = 9
