How can the Distributive Property help when you are multiplying by a two-digit number

Mathematics

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

It states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

Here, calculating 8 × 27 can made easier by breaking down 27 as 20 + 7 or 30 − 3.

Distributive Property is easy to remember if you recall that "multiplication distributes over addition".They write this property as "a(b + c) = ab + ac". In numbers, this means, 2(3 + 4) = 2×3 + 2×4.

The distributive property explains that multiplying two numbers (factors) together will result in the same thing as breaking up one factor into two addends, multiplying both addends by the other factor, and adding together both products.

I got this from google for a more definitive answer than my original.

I hope this helps, if not, comment below please!!!

F(x) = 4x – 10<br> g(x) = -8x2 + 6x – 10<br> Find: f(x) · g(x)
Lilit [14]

Answer: f(x) · g(x)=-32x³+104x²-100x+100

Step-by-step explanation:

Since we are given f(x) and g(x), all we have to do is multiply them together.

f(x) · g(x)=(4x-10)(-8x²+6x-10)                              [distribute by FOIL]

f(x) · g(x)=-32x³+24x²-40x+80x²-60x+100         [combine like terms]

f(x) · g(x)=-32x³+104x²-100x+100

Now, we have multiplied them together, we have f(x) · g(x)=-32x³+104x²-100x+100.

Find the area of an equilateral triangle if a side is 8 times the square root of 3
irga5000 [103]

The area would be about 83.14.

You can find this by starting with the formula for the area of an equilateral triangle:

A = \frac{\sqrt{3}}{4}  S^{2}

In this equation, A is the area and S is the side. So we'll just plug in the value.

A = \frac{\sqrt{3}}{4}  S^{2}

A = \frac{\sqrt{3}}{4} (8\sqrt{3})^{2}

A = \frac{\sqrt{3}}{4}  24

A = 83.14

On a piece of paper, use a protractor to construct a triangle with angle measures of 60° and 80°. Select from the drop-down menu
maria [59]
The sum of interior angles of a triangle must add up to 180 degrees

if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse

if the triangle has an angle that is 90 degrees, then it is considered right

if all angles are less than 90, then it is acute

find the missing angle "x"

180=60+80+x

is angle x less than, greater, or equal to 90 degrees?

trasher [3.6K]

Answer:

<h2>x = 10.1</h2>

Step-by-step explanation:

9x-3.3=6.8+8x\qquad\text{add 3.3 to both sides}\\\\9x-3.3+3.3=6.8+3.3+8x\\\\9x=10.1+8x\qquad\text{subtract 8x from both sides}\\\\9x-8x=10.1+8x-8x\\\\x=10.1
