1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.
2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.
3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.
Hope this helps!!!
r= 9 because 45/5 is 9 and it works the same way for the rest of the problems.
Answer:
1,260 sq ft
Step-by-step explanation:
FORMULA TO FIND AREA OF A RECTANGLE: L*W, l=length, w=width
we can divide the figure into three other rectangles
rectangle one) length=20 width=10
so 20*10=200
rectangle 2) length=45, width=20
so 45*20=900
rectangle 3) length=20 width=8
so 20*8=160
now we add up the areas of the 3 rectangles to find the area of our figure
200+900+160=1,260 sq ft
hope this helps!
