Answer:
B
Step-by-step explanation:
Area of a trapezoid = (1/2)*(base1+base2)*height
Area = (1/2)*(15+7)*height
DC is 7 which means EF is also 7.
AB = 15
AB - EF = AE + FB = 8
And AE = FB we know that AE is 8/2 = 4
We were given AD = 5. We have a 3-4-5 right triangle and therefore DE is 4. The height of the trapezoid is 3 ft.
Area = 1/2 (15+7)*(3)
Area = (1/2)*22*3
Area = 11 * 3
Area = 33 ft^2
Your answer is B
Answer:
Step-by-step explanation:
(x - 1) × ( cancel the factor (x - 1) on numerator and denominator
= 1
[ In the same way 2 × 
= 1 ]
The required rational expression is
Answer:
Sun-Li will be able to ride 12 rides. (30-5)/2=24
Step-by-step explanation:
We know that
Population density<span> is a measurement of population per unit area
</span>[population density]=population/area-----><span>7,112,688/426.25----> 16686.66
16686.66----------> 16687 person/square mile
the answer is
</span>16687 person/square mile
9, 4, -1, -7
Arithmetic because it has a common difference of 5.
4, 10, 16, 22
Arithmetic because it has a common difference of 6.
2, -6, 18, -54
Geometric because it has a common ratio of -3.
4, 4, 4, 4
Both because it has a common difference of 0 and a common ratio of 1.
Hope this helps :)
