The answers have square roots among the choices so we probably shouldn't use that calculator button.
We can't just apply the area of the trapezoid formula
where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.
It will be 10 less the leg of that right triangle, which we calculate as
Now we can apply the trapezoid formula. We have
Choice b
Answer:
3 < x < 17
Step-by-step explanation:
Given 2 sides then the possible range of the third side x is
difference of 2 sides < x < sum of 2 sides , that is
10 - 7 < x < 10 + 7
3 < x < 17
This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded
<h3>Inequality expression</h3>
Inequalities are equation not separated by an equal sign
Given the inequality expression
4x − 5 ≤ 19
4x ≤ 19 + 5
4x ≤ 24
x≤ 6
This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded
Given the equation
4x + 3 = 23
4x = 23 - 3
4x =20
x = 5
Hence 5 is the solution from the given set

Answer:
b= 4.260
Step-by-step explanation:
28^3=2165
divide both sides by 28
x^3= 2165/28
x=(2165/28)^(1/3)
x= 4.260232
