Which expression is the factored form of−4.5n+3?

Mathematics
1 answer:
katen-ka-za [31]3 years ago
7 0

Answer: Choice C

Explanation:

We can verify the answer by distributing the -3 through to each term inside

  • -3 times 1.5n = -4.5n
  • -3 times -1 = 3

This shows that -3(1.5n-1) is the same as -4.5n+3. The process of factoring out the GCF like this is basically the reverse of the distributive property.

The distributive property in general is a(b+c) = ab+ac

Serga [27]

<u>Answer</u>:

the length of chicken coop and the garden is of 40 feet.

<u>Explanation</u>:

Given that the garden is the length of the chicken coop, equal length

→ 3x + 12 = 6x – 16

→ 3x - 6x = -16 - 12

→ -3x = -28

→  x = \frac{-28}{-3}

→ x= 9\frac{1}{3}

→ x = 9.33 feet.

  • The garden length = 3(  \frac{-28}{-3}) + 12 → 40 feet
  • the chick coop length should be same as the garden length.

kipiarov [429]

The difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper

What is the difference of depths between them, and which trench is deeper?

The given parameters are:

Mariana Trench = 11 km

Japan Trench = 9 km

The Mariana Trench is deeper because 11 is greater than 9

The difference between the depth is

Difference = 11 km - 9 km

Difference = 2 km

Hence, the difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper
