Answer:

The answer would be 6.

Step-by-step explanation:

Assuming, Amy doesn't have a sweet tooth, she's only giving party favors to her own guests.

There are 3 bags of 12 party favors each. This gives us a total of 36 party favors.

There are 6 guests and so to evenly split the party favors, we must split 36 into 6 groups, giving us 6 party favors in each group.

COMPUTATION:

3 x 12 = 36

36 / 6 = 6

Hope this helps!

In your own words, describe the process of multiplying binomials using the FOIL method. You can either write a paragraph describ
neonofarm [45]

Answer:

We can describe FOIL using the distributive property of multiplication. For real numbers x, y, and z the distributive property of multiplication states that

(x + y)z = xz + yz

Now let z = v + w, where v and w are real numbers.

Then (x + y)(v + w) = x(v + w) + y(v + w)

Here, we can again use the distributive property of multiplication to get

x(v + w) + y(v + w) = xv + xw + yv + yw

Hence, it follows that

(x + y)(v + w) = xv + xw + yv + yw

This is the method of FOIL (first: xv, outside: xw, inside: yv, last: yw)

For example, (1 + 2)(3 + 4) = 21 \\\text{and} \\1(3) + 1(4) + 2(3) + 2(4) = 3 + 4 + 6 + 8 = 21

The triangle and the trapezoid have the same area. Base b2 is twice the length of base b1. What are the lenghts of the bases of
Sati [7]

Answer:

<h2>The lengths of the bases of the trapezoid:</h2><h2>42/h cm and 84/h cm.</h2>

Step-by-step explanation:

The formula of an area of a triangle:

A=\dfrac{bh}{2}

<em>b</em><em> </em>- base

<em>h</em> - height

We have <em>b = 21cm, h = 6cm</em>.

Substitute:

A=\dfrac{(21)(6)}{2}=63\ cm^2

The formula of an area of a trapezoid:

A=\dfrac{b_1+b_2}{2}\cdot h

<em>b₁, b₂</em> - bases

<em>h</em><em> - </em>height

We have <em>b₁ = 2b₂</em>, therefore <em>b₁ + b₂ = 2b₂ + b₂ = 3b₂</em>.

The area of a triangle and the area of a trapezoid are the same.

Therefore

\dfrac{3b_2}{2}\cdot h=63         <em>multiply both sides by 2</em>

3b_2h=126          <em>divide both sides by 3</em>

b_2h=42         <em>divide both sides by h</em>

b_2=\dfrac{42}{h}

b_1=2b_2\to b_1=2\cdot\dfrac{42}{h}=\dfrac{84}{h}

Fill in the blanks to make the equation true. (x−9)(x+2)=x^2________ −18
Andrews [41]

Answer:

x² - 7x - 18

Step-by-step explanation:

Remember to follow FOIL.

First, multiply the first. (x)(x) = x²

Next, multiply the second. (x)(2) = 2x

Then, multiply the third. (-9)(x) = -9x

Finally, multiply the last. (-9)(2) = -18

Combine like terms: x² + 2x - 9x - 18

x² - 7x - 18

x² - 7x - 18 is your answer.
