Answer:
B. {0, 5, 6, 7}.
Step-by-step explanation:
The range is the set of y-values.
The solution is : 2,457 mm^2, is the area of the heptagon.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
The dimensions of each of the triangles in terms of their bases and heights will be;
26 mm by 27 mm
Mathematically, the area of one of the triangles will be ;
1/2 * base * height
= 1/2 * 26 * 27
= 351 mm^2
So the area of the heptagon is the sum of the areas of all of the triangles
mathematically, that would be;
351 * 7
= 2,457 mm^2
Hence, The solution is : 2,457 mm^2, is the area of the heptagon.

Answer: x = 8
Step-by-step explanation: So you have 3 sides and 3 numbers. Identify the side that has a number without a variable. (This goes for both triangles) Then you divide the 1st number by the 2nd. In this case it would be 20 or side "B" divided by 5 or side "E", which equals 4. You then take 4 and multiply it by 4 or side "D" (Because it's the only other side that does not have a variable) and you take your answer (16) and 2x or side "A", and make an equation. The equation would be : 2 * x = 16. Now solve the equation. Your answer is : x = 8.
Answer: 20
Step-by-step explanation:
x = 7
y = 3
2x + 2y = 2(x + y)
2(7+3) = 2 • 10 = 20
Answer:
20
Step-by-step explanation:
2(7) + 2(3)
14 + 6
20
