The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)
<h3>
Area of Polygon</h3>
The polygon is composed of a triangle and a rectangle.
Area of the polygon = Area of Triangle + Area of Rectangle
Area of Rectangle = length × width
Length = 21 cm
Width = 14 cm
Area of rectangle = 21 × 14 = 294 cm²
Area of Triangle = 1/2(base × height)
Base = 21 - 10 = 11 cm
Height = 18 - 14 = 4 cm
Area = 1/2(11 × 4) = 22 cm²
Therefore:
Area of Polygon = 294 + 22 = 316 cm².

Answer: C. g(-2) = -5
<u>Step-by-step explanation:</u>
g(-2) is when you replace all of the x's in the function with -2
g(x) = -3x² - 2x + 3
g(-2) = -3(-2)² - 2(-2) + 3
= -3(4) + 4 + 3
= - 12 + 4 + 3
= -12 +7
= -5
Answer:
c = -25
Step-by-step explanation:
Multiply the denominator by -7 on both sides, you would then get the equation c + 32 = 7 in which the -7 on the left side cancels out. Subtract 32 on both sides to get the c value which is -25.
Answer:
it's should be B
reflection over the x-axis
To get the answer, first, you need to turn them into decimals
16 1/5 =16.2 and 5 2/5 =5.4
then all you need to do is to divide the numbers
16.2 divided by 5.4 equals to 3
so the answer is 3
