The base of trapezoid is equal to a = 25.5 cm and b = 43.5 cm.

The area of trapezoid is A = 1656.

The formula for the area of trapezoid is,

$A=\frac{a+b}{2}\cdot h$

Substitute the values in the formula to obtain the height of trapezoid.

$\begin{gathered} 1656=\frac{25.5+43.5}{2}\cdot h \\ h=\frac{1656\cdot2}{69} \\ h=24\cdot2 \\ =48 \end{gathered}$

So height of trapezoid is 48 cm.

Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4
Cost = (3,500) * 1.16985856 
Cost = 4,094.50

Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same op

FromTheMoon [43]

Answer:

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

Step-by-step explanation:

First let us evaluate the value of both the expressions.

$(14+12)\times (8+12) = 26\times 20 = 520$

$(14\times 12)+(8\times 12) = 168 + 96 = 264$

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

$(14+12)\times (8+12)$ is greater by the expression $(14\times 12)+(8\times 12)$ by a value of 520 - 264 = 256.
