the area, a, of a trapezoid is given by the formula a=1/2h(c+d), where h is the height and c and d are the lengths of the bases rearrange the formula so that the height h of the trapezoid can be determined given the area and the lengths of the bases enter your answer in the box
Answer:
this is algebra remember algebra rules and thing really hard
Step-by-step explanation:
The formula for the height of the trapezoid will be h = 2A/(c+ d).
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
Given a trapezoid with side lengths c and d and perpendicular distance as h
So, the area formula will be
A = (1/2)h(c + d)
Multiply both sides by 2
2A = h (c + d)
Divide by c + d into both sides
2A/(c + d) = h
Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:
Answer:
Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
Circle: The area of a circle is pi times the radius squared (A = π r²).
Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.

The measures of three line segments are given in each set.
Which set of line segments cannot form a triangle?
20.2 m, 20.4 m, 20.6 m
32.8 m, 48.2 m, 81.1 m
12.8 m, 25.7 m, 35.9 m
35.6 m, 49.9 m, 83.2 m
Answer:
second option: 32.8 m, 48.2 m, 81.1 m
Step-by-step explanation:
20.2 m + 20.4 m = 40.6 m. which is bigger than 20.6 m. so yes
32.8 m + 48.2 m = 81 m. which is smaller than 81.1 m. so no
12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes
35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes

Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.
Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Answer:
False
Step-by-step explanation:
Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:
[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]
We can do the same for the square in which ON = 6 because it's a square:
[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]
Now let's compare them:
8.5 X 2 = 17 so OM X 2 is not equal to SQ
The sentence is false.

Which of the following is an equation of the line through (3, -1) and (−2, 14)?
A) y = 1/3x - 2
B) y = -1/3x
C) y = 3x - 10
D) y = -3x + 8
the required equation of the line is y = -3x + 8. option D is correct.
Given that,
To determine an equation of the line through (3, -1) and (−2, 14).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3, -1) and (−2, 14)
m = 14 + 1 / -2 - 3
m = -15 / 5
m = -3
So, equation D contains the slope -3.
Thus, the required equation of the line is y = -3x + 8. option D is correct.
