The area of the composite shape in the diagram given is: 100 square inches.
<h3>How to Find the Area of a Composite Figure?</h3>
Area of a composite figure = sum of the areas of the shapes that make up the figure.
Area of the composite shape = 2(area of triangle) = 2(1/2bh)
Area of the composite shape = 2(1/2×10×10)
Area of the composite shape = 100 square inches.

Answer:
c • (15c2 + 14)
Step-by-step explanation:
14c + (3•5c3)
3.1 Pull out like factors :
15c3 + 14c = c • (15c2 + 14)
Answer: B, a reflection across the y axis
Explanation: The y axis would be the line of reflection in this case, so for the shape to map onto itself, it would need to be reflected across the y axis.
I apologize in advance if it’s wrong but I hope it helps a little.
Answer:
x=-2 and y=2
Step-by-step explanation:
Do simultaneous equations
-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>
-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>
56x - 28y = -168
-56x + 56y = 224
<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>
<em> </em>28y = 56
∴y = 2
-8x + 4y = 24
-8x + 4(2) = 24
-8x = 16
∴x=-2
Lemme know if you have questions :D
