Equivalent Expressions & the Distributive Property-
A tiny house has a length of 25 feet. The width of the kitchen is 3 feet, and the width of the
remaining living space is 12 feet.
Which expression represents the area
of the tiny house?
3(12+25)
25-3+12
25(3+12)
3-12 +25
25 ft
3 ft
12 ft
Answer: The area of the tiny house can be represented by multiplying the length of the house by the width. Since the width of the kitchen is 3 feet, and the width of the remaining living space is 12 feet, the total width of the house is 3+12 = 15 feet.
So the area of the tiny house is 25 ft * 15 ft = 2515 = 375 sq ft.
The expression that correctly represents the area of the tiny house is 25 * 15 =375.
So the correct answer is 2515 = 375 ft^2
The other expressions you gave are not the correct representation of the area of the house
3(12+25) = 3 * 37 = 111 ft^2
25-3+12 = 25 - 3 + 12 = 34 ft^2
25(3+12) = 25 * 15 = 375 ft^2
3-12 +25 = 3 - 12 + 25 = 16 ft^2
25 ft , 3 ft and 12 ft are not represent the area of the house.

The wall paper Jeff wants to use comes in rolls that are 1 yard wide and 10 yards long. How many square feet of wall paper are in each roll?
Answer:
Each roll of wallpaper has an area of 90 square feet.
Step-by-step explanation:
In order to find the number of square feet of wallpaper in each roll, we first need to calculate the total area of the wallpaper in the roll. The area is the product of the length and width of the roll.
The width of each roll is 1 yard, and the length of each roll is 10 yards.
Area of the wallpaper = width x length = 1 yard x 10 yards = 10 square yards
Now we need to convert the area from square yards to square feet, as the area of wallpaper is usually measured in square feet.
1 yard = 3 feet
So we need to multiply the area in square yards by the conversion factor, which is 9.
10 square yards = 10 square yard * 9 = 90 square feet
Therefore, each roll of wallpaper has an area of 90 square feet.
It's important to note that while calculating, the units should be consistent i.e area of a length (yard) multiplied with a width(yard) will give the area in square yards, which we converted to square feet by considering the conversion factor of 1 yard = 3 feet.

If Goran invested his savings in two investment funds. The amount that Goran invest in Fund B, if the total profit from the two funds together was 500?
How to find the amount invested?Amount Invested in Fund A = x
Amount invested in Fund B = x+7000
Profit from fund A = 0.04x
Profit from fund B = 0.02(x+7000)
0.04x +0.02(x+7000) = 500
0.04 +0.02x + 140 =500
Combine like terms

Divide both side by 0.06x
x = 360 /0.06
x = 6,000
Amount Invested in Fund A = x =6,000

Step-by-step explanation:
Given f(x) = -3x + 1, solve for a when ƒ(x) = −5.
Clearly f(x) is one-one onto function so it is invertible so ƒ(x) is y + -5 /3.
What one-one onto function ?Each element of one set, let's say Set (A), is mapped with a particular element of another set, let's say Set (B), where A and B are two separate sets. This is known as a one-to-one function or one-to-one mapping. 1-1 is another way to write it. If f(x) = f(y) means that x = y, then f is one to one in terms of function.
Let y = f(x) = -3x + 1
Clearly f(x) is one-one onto function so it is invertible.
⇒y = -3x − 1 ⇒ x = y+1 /-3
∴f (x)= -5
y + -5 /3
Clearly f(x) is one-one onto function so it is invertible so ƒ(x) is y + -5 /3
