What is the algebraic property of 4(x+y)=4x+4y

1 answer:

5 0

Hey there!

Your answer is: the distributive property.

The distributive property is defined as:

a(b+c) = ab+ac

That's exactly what we're doing here. We're taking that 4 and doing:

4(x) + 4(y) = 4x + 4y

Hope this helps!

Igoryamba

Answer:

6x^2 +12x -1

Step-by-step explanation:

The perimeter is the sum of the two leg lengths and the base length:

P = 2(3x^2 +4x +2) +(4x -5)

= 6x^2 +8x +4 +4x -5

P = 6x^2 +12x -1

Your friend can do 1/3x in an hour.

<u>Together you can do:</u>

1/2x + 1/3x = 5/6x of a job in an hour

<u>You need time to finish the job:</u>

x ÷ 5/6x = 6/5 = 1.2 hours

How can you write the expression with the rationalized denominator? ^3 sqrt 7/ ^3 sqrt 49

levacccp [35]

Answer: ∛(49) / 7

Explanation:

1) Given expression:

$\frac{ \sqrt[3]{7} }{ \sqrt[3]{49} }$

2) Notice that 49 = 7².

3) With that in mind, rationalize by multiplying numerator and denominator by ∛7:

$\frac{ \sqrt[3]{7} }{ \sqrt[3]{49} } \frac{ \sqrt[3]{7} }{ \sqrt[3]{7} } = \frac{ \sqrt[]{7^2} }{ \sqrt[3]{7^3} } = \frac{ \sqrt[3]{49} }{7}$
