Find the area of the figure
1 answer:
Answer:
<h2>A = 252</h2>Step-by-step explanation:
It's a trapezoid.
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
<em>(look at the picture)</em>
Use the Pythagorean theorem to calculate the length <em>x</em>:
<em>subtract 144 from both sides</em>
Substitute:
[tex]A=\dfrac{30+12}{2}\cdot12=(42)(6)=252[/txt]

For this case we have to represent the following expression algebraically:
"10 less than x is -45"
So:
10 less than x is represented as:
Then, the complete expression is represented as:
Adding 10 to both sides of the equation:
Thus, the value of the variable is
Answer:
Answer:
Point C: (4, 0)
Step-by-step explanation:
Parallelograms are quadrilaterals with two pairs of parallel sides, this means they will have the same slope between two line segments.
point slope form between two points: y - y1 = m (x - x1)
point A (2, 6) and D (4,4):
slope: point form, 6 - 4 = m(2 - 4)
2 = -2m
m (slope) = =
now that you know the change in position, apply this to vertice B to get the position of the final vertice.
B(2, 2)
C (2 +2, 2-2) = C(4, 0)
The final position of C vertice for parrallelogram A(2,6), B(2,2), D(4,4) will be C(4,0)
