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)".

On an architect’s drawing of a house, 1 inch represents 1.5 feet. If the bedroom window is 5 inches long on the drawing, how many feet long will it be in the actual house?
Brainliest if you answer
Answer:
3.33~
Step-by-step explanation:
Since 1 inch represents 1.5 feet, you'll divide 5 inches by 1.5. And get 3.33 repeating
Answer:
7.5 feet
Step-by-step explanation:
REASONAccording to the given scale, 1 inch on the drawing represents 1.5 feet in the actual house.
Therefore, to find the length of the bedroom window in feet, we need to multiply the length on the drawing (5 inches) by the scale factor (1.5 feet/inch):
5 inches * 1.5 feet/inch = 7.5 feet
Hence, the bedroom window will be 7.5 feet long in the actual house.

find the surface area of the triangular prism shown below.
Answer:
136 units²
Step-by-step explanation:
The surface area (SA) is calculated as
SA = area of base + area of 2 congruent sloping faces + area of 2 triangular ends
area of base = 6 × 7 = 42 units²
area of sloping faces = 2 (7 × 5) = 2 × 35 = 70 units²
area of triangular faces = 2 × [tex]\frac{1}{2}[/tex] × 6 × 4 = 6 × 4 = 24 units²
SA = 42 + 70 + 24 = 136 units²
Four students factor the expression 16x+12. The table shows the students’ responses.
student 4 factors the expression correctly.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
The expression 16x + 12 can be factored out by finding the greatest common factor (GCF) of its terms,
which is 4, and factoring out 4:
16x + 12 = 4(4x + 3)
Thus, the factored form of 16x + 12 is 4(4x + 3).
Therefore, student 4 factors the expression correctly.
