Formula for "Area of a trapezoid" :
____________________________________________
Area = (1/2) * (base length 1 + base length 2) * height;
or: A = (1/2) * (b + B) * h.
We are missing the value for "b" one of the base lengths.
However, since: A = 68² (given) ; B (the other base length) = 21; and the perpendicular height, "h" = 4 ; we can plug this values into the formula, and solve for "b" ;
________________________________________________
A = (1/2) * (b + B) * h ; ↔ 68² = (1/2) * (b + 21) * 4 ;
↔ <span>4624 = 2 (b + 21) = 2b + 42 ;
</span> ↔ <span>4624 = 2b + 42 ;
</span> ↔ <span>2b + 42 = 4624 ;
Subtract "42" from each side of the equation:
2b + 42 - 42 = 4624 - 42 ;
to get: 2b = 4582 ;
</span>___________________________________________________
Now, divide each side of the equation by: "2" ; to isolate "b" on one side of the equation; and to solve for "b" ;
___________________________________________________
2b / 2 = 4582 / 2 ;
___________________________________________________
to get: b = 2291 units.

Answer:
g(g(-2))
g(-8)
-32
This is the correct solution
Answer:
x=5
Step-by-step explanation:
x+5 = -3x+25
Add 3x to each side
x+3x+5 = -3x+3x+25
4x +5 = 25
Subtract 5 from each side
4x+5-5 = 25-5
4x = 20
Divide each side by 4
4x/4 = 20/4
x =5
I don't really know how the table works, but there are two cups in a pint, so 5 pints * 0.5 pints would be 2.5 pints, and 2.5 pints divided by 2 pints would be 1.25 pints?
Answer:
f(5) = 17
Step-by-step explanation:
You just plug in 5 for x:
f(5) = 3(5) + 2
f(5) = 15 +2
f(5) = 17
Hope this helps!
