Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)

Mathematics

Arada [10]2 years ago
4 0

For this case we have the following expression:

4x + 2 (2x-5) - (3-5x)

Applying distributive property to the terms within parentheses taking into account that:

- * + = -\\- * - = +

We have:

4x + 4x-10-3 + 5x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

4x + 4x + 5x-10-3 =\\13x-13

Thus, an equivalent expression is:

13x-13

Answer:

13x-13

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function p(t) = 6t, where t represents t
Neko [114]

Answer:

A)   A[p(t)] = 36πt²

B)   7234.56 square units

Step-by-step explanation:

               

<u>Given functions</u>:

\begin{cases}p(t)=6t \\ A(p)=\pi p^2 \end{cases}

<u>Part A</u>

To find the area of the circle of spilled paint as a function of time, substitute the function p(t) into the given function A(p):

\begin{aligned}A(p) & = \pi p^2\\\\ \implies A[p(t)] & = \pi [p(t)]^2\\& = \pi (6t)^2\\& = \pi 6^2 t^2\\& = 36\pi t^2\end{aligned}

<u>Part B</u>

Given

  • t = 8 minutes
  • π = 3.14

Substitute the given values into the equation for A[p(t)} found in part A:

\begin{aligned}A[p(8)] & = 36\pi t^2\\& = 36 \cdot 3.14 \cdot 8^2\\& = 36 \cdot 3.14 \cdot 64\\& = 113.04 \cdot 64\\& = 7234.56\:\: \sf square\:units\end{aligned}

Therefore, the area of spilled paint after 8 minutes if 7234.56 square units.

How many 5/16 foot pieces of wood can you cut from a board that is 1 19/16 feet long?​
lapo4ka [179]

Answer:

5 pieces

Step-by-step explanation:

To find the number of pieces divide 1 7/8 by 3/8

Change 1 7/8 to an improper fraction

substitute this value into the equation

to solve this complex fraction remove the bottom fraction by multiplying both the top and bottom fractions by the inverse of the bottom fraction.

Multiplying by the inverse results in a product of 1 so the result is

dividing by 1 gives just the top fraction.

Pyramid A has a square base with side lengths of 6 meters, and 4 triangular sides with a base of 6 meters and height of 7 meters
Fudgin [204]

Step-by-step explanation:

6 times 9 is 54.

54 divided by 2 is 27 volume ( recipitor) is 27 for no.1

6 times 7 is 42

42 divided by 2 is 21 is the recipitor or volume for no.2

there fore a has a bigger base surface

as base is measured by recipitorial angles

sorry if this isnt the right answer or what u wanted but I know it this way
