Answer:
Both Scott and Tara have responded correctly.
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
A=(1/2)[b1+b2]h
we have
b1=16 cm
b2=24 cm
h=8 cm -----> <em>Note</em> The height is 8 cm instead of 18 cm
substitute
A=(1/2)[16+24](8)
A=160 cm²
<em>Verify Scott 's work</em>
<em>Note</em> Scott wrote A = (1/2)(24 + 16)(8) instead of A = 2(24 + 16)(8)
Remember that the Commutative Property establishes "The order of the addends does not alter its result"
so
(24+16)=(16+24)
A = (1/2)(24 + 16)(8)=160 cm²
<em>Verify Tara's work</em>
<em>Note</em> Tara wrote A = (1/2)(16+24)(8) instead of A = (16 + 24)(8)
A = (1/2)(16+24)(8)=160 cm²

Answer:
Step-by-step explanation:
I think the quotent is 5, but I recommend waiting for sumone else to answer. Because 31.5 divided by 1.4 equals 22.5 but I'm not sure.
Answer:
![x=29](https://tex.z-dn.net/?f=x%3D29)
Step-by-step explanation:
Given equation :
![\frac{(7+2x)}{5} =13](https://tex.z-dn.net/?f=%5Cfrac%7B%287%2B2x%29%7D%7B5%7D%20%3D13)
Making the terms of 'x' to one side and constants to the other.
![(7+2x)=13*5](https://tex.z-dn.net/?f=%287%2B2x%29%3D13%2A5)
![7+2x=65](https://tex.z-dn.net/?f=7%2B2x%3D65)
![2x=65-7](https://tex.z-dn.net/?f=2x%3D65-7)
![2x=58](https://tex.z-dn.net/?f=2x%3D58)
![x=\frac{58}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B58%7D%7B2%7D)
![x=29](https://tex.z-dn.net/?f=x%3D29)
So, the value of 'x' is 29.
