Answers

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

Answers

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:

REASON

According 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.

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.
