B + 7.5 = 4.8
-7.5 -7.5
-----------------------
b = -2.7
Hope this helps!!!!!
You can also check your answer by doing replacing the number with the variable ( don't just write the anwser just because you know it, since its pre algebra you have to do it algebraically like above)
-2.7 + 7.5 = 4.8
Hope it helps!
Not 100% sure if this is how you do it but I tried.

The factors should add to the b value and multiply to the c value.
Final answer: (x-9)(x-7)
Check:
-9*-7=63
-9-7=-16
You don't need the apothem if the side length is known, the area can be expressed as:
A(n,s)=ns^2/(4tan(180/n)), n=number of sides and s=side length so
A(7,28)=(7*28^2)/(4tan(180/7))
A≈2848.987 ft^2
A≈2849 ft^2 (to the nearest tenth of a square foot)
Answer:
b = 65
Step-by-step explanation:
b is the y- intercept
if you start to graph 6x from the two points that are already given then it'll find the y-intercept which is b
here's the graph
