Answer:

The 2nd one would be different from the first because you are adding 3.

Solve for u

Sergio039 [100]

U/9 = 8/12 u = 6

Step 1: Cancel the common factor (4)

u = 2
—- —-
9 3

Step 2: multiply both sides by 9

9u 2 * 9
—- = ——-
9 3

Step 3: simplify

2 *9 = 18

18 ÷ 3 = 6

u = 6

Ana Completed 40% of her homework assignment How to Assignments contain 30 math problems how many problems does Anna still need

yulyashka [42]

Answer:

Step-by-step explanation:

30*0.4=12

This means 40% of 30 is 12 and Ana has completed 12 problems.

30-12 = 18, so she still needs to do 18 problems.

50 POINTS!!! Plz show work questions are in the addon

1. Each term in this polynomial has a common factor of $3x^3$ :

$12x^6-9x^4+18x^3=3x^3(4x^3-3x+6)$

2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.

$(3x-5)(2x^2+7x-3)=3x(2x^2+7x-3)-5(2x^2+7x-3)$

$(3x-5)(2x^2+7x-3)=(6x^3+21x^2-9x)+(-10x^2-35x+15)$

$(3x-5)(2x^2+7x-3)=6x^3+11x^2-44x+15$

3. You can use the same approach as in (2), or recall that $(a+b)^2=a^2+2ab+b^2$ :

$(5x-4y)^2=(5x)^2+2(5x)(-4y)+(-4y)^2$

$(5x-4y)^2=25x^2-40xy+16y^2$

4. Recall that a difference of squares can be factored as $a^2-b^2=(a-b)(a+b)$ . So

$(2x^2-7)(2x^2+7)=(2x^2)^2-7^2$

$(2x^2-7)(2x^2+7)=4x^4-49$

Which of the following is defined by a line parallel to one side of a triangle

Katarina [22]

Answer:

Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Step-by-step explanation:

Triangular Proportionality Theorem states that:

If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

Let us consider the triangle ΔABC as shown in attached figure.

$DE$ ║ $AC$

then

$\frac{BD}{DA} = \frac{BE}{EC}$

Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
