The answer is a the length is 69 and the base is 115 and if you multiply 115*69 you will get 7935 square units
Answer:
y = 7x+2
Step-by-step explanation:
Let x be the number of minutes Jim used
105.60 = 75+0.30(x−1000)
105.60=75+0.30x−300
105.60=0.30x−225
1056=3x−2250
1056+2250=3x
3306=3x
x=1102
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.
<h3><u><em>
Your answer is 80.</em></u></h3>
Your expression is ambiguous.
Do you mean a + (2/5)a^2 + 3?
or perhaps a + 2 / (5a^2) + 3? Use parentheses for added clarity.
If you meant a + (2/5)a^2 + 3, then
(2/5)a^2 + 1a + 3 (this can't be simplified further)
