What multiplication expression can be broken apart into (3x4) + (3x4) using the distributive property

2 answers:

The original expression here might be (4x3) + (4x3). This is because the distributive property simply moves around numbers, but will not change the value of the equation, as in the question we are looking at here.

One possible answer is:

3(8)

Explanation:

The distributive property states that we multiply everything inside parentheses with the term outside parentheses. Algebraically, it is a(b+c) = ab+ac.

This means we need to split 8 up into a sum. Using 4+4, we have 3(8) = 3(4+4) = 3(4) + 3(4)

Calculate a) 20% of £150 b) 15% of 80 kg c) 85% of 2 500 m

GaryK [48]

Step-by-step explanation:

$p\%=\dfrac{p}{100}$

$a)\\20\%=\dfrac{20}{100}=\dfrac{2}{10}=0.2\\\\20\%\ of\ \£150\to0.2\cdot\£150=\£30\\\\b)\\15\%=\dfrac{15}{100}=0.15\\\\15\%\ of\ 80kg\to0.15\cdot80kg=12kg\\\\c)\\85\%=\dfrac{85}{100}=0.85\\\\85\%\ of\ 2500m\to0.85\cdot2500m=2125m$

. (08.01 MC) 1. Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14

icang [17]

Answer:

602.88 in³

Step-by-step explanation:

Formula for volume of a cylinder = πr² · h

radius (r) = 1/2(diameter)

1. Set up the equation

radius = 4

(3.14)(4²)(3·4)

2. Solve

3.14(16)(12) = 602.88 in³

Formula for volume of a cone = 1/3πr² · h

The formula of a cone is 1/3 the volume of a cylinder. Therefore, a cone that fits perfectly within the dimensions of a cylinder would have a volume equal to 1/3 of the volume of the cylinder.

1. Set up the equation and solve

36 ÷ 3 = 12

What is the value of x? Enter your answer in the box. x =

Arturiano [62]

I believe x= 32. 2(32) - 4 would equal 60. And due to all the angles and sides being the same, this would be correct.

bc you need to do multiplication first so the equation turns out to be

10 - 1000 - 23

so then that turns to -1013 if you calculate left to right
