Answer:

A = 192 in²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 12, b₁ = AB = 14 and b₂ = DC = 2 + 14 + 2 = 18, then

A = $\frac{1}{2}$ × 12 × (14 + 18) = 6 × 32 = 192 in²

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly

frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

$y-7 = -\frac{5}{2} (x+6)$

$y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8$ <------ Answer

Hope that helps!
