Answer:
63 yd²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (a + b)
where a and b are the parallel bases and h the perpendicular height.
Here a = 8, b = 10 and h = 7, thus
A = 0.5 × 7 × (8 + 10) = 0.5 × 7 × 18 = 63 yd²
Answer:
27 x 7=X
Step-by-step explanation:
When y varies inversely as x it can be expressed as follows:
If we write the general equation for this
When y=3 and x=4 we can calculate de value of A
Then the equation that describes an inverse variation between x and y is_
Below are the choices:
<span>-1/2
0
-1
non
</span>
The exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution,
<span>4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2</span>
