What is the surface area of this point
Kaylis [27]

Answer:

The answer is 30ft.

Step-by-step explanation:

To find the surface area of a rectangle, we use the formula L(2) + W(2) + H(2)

Our length is 7ft

Our Width 2ft

Our height is 6ft

Let's plug our numbers into our equation:

7(2) + 2(2) +6(2)

= 14 + 4 + 12

=30 ft.

Answer:

Slope = -2

Step-by-step explanation:

Given the two points, (-4, 10) and (0, 2), the error in the given problem is the incorrect substitution of values into the formula. It should have been formatted as follows:

Let (x₁, y₁) = (-4, 10)

    (x₂, y₂) = (0, 2)

The formula for solving for the slope of the line is:

m = (y₂ - y₁)/(x₂ - x₁)

where <em>m</em><em> </em>represents the <u>slope</u> of the line.

Substitute the given values into the formula to solve for the slope:

m = (y₂ - y₁)/(x₂ - x₁)

m = \frac{2 - 10}{0 - (-4)}

m = \frac{-8}{0  + 4 }

m = -8/4

m = -2

Therefore, the slope of the line is -2.

When adding two numbers, such as 123 and 423, care is taken to first line them up and then add like digits. How does expanding t
zavuch27 [327]
Think of 10^2, 10^1, and 10^0 as x^2, x^1, and x^0.
When you add polynomials, you can only combine like terms.
When you add expanded numbers, you can only combine like powers of 10.

123 + 423 =

= (100 + 20 + 3) + (400 + 20 + 3)

= (1 * 10^2 + 2 * 10^1 + 3 * 10^0) + (4 * 10^2 + 2 * 10^1 + 3 * 10^0)

= (1 * 10^2 + 4 * 10^2) + (2 * 10^1 + 2 * 10^1) + (3 * 10^0 + 3 * 10^0)

= 5 * 10^2 + 4 * 10^1 + 6 * 10^0

= 500 + 40 + 6

= 546
