Answer:

15.12

Step-by-step explanation:

3.6 x 4.2

first aline the decmials like you would regularly do to multiply.

Then multiply 2 x 6=12 and then 2 x 3=6 and put them down were you would already do noramly multiplying.

and then muliply 4x6=24 and 4x3=12 and do the same thing as you would do normaly and then add 72 and 144 to get 1512 and then count your decmail placing. which is 2 placeing in total which makes 1512 into 15.12

and now you done!

Example of how it should look...

3 . 6

× 4 . 2

+ 7 . 2

+ 1 4 4

= 1 5 1 2

Aliun [14]

Answer:

(1): "*-5x2y" was replaced by "*(-5x2y)".

(2): "x2" was replaced by "x^2". 1 more similar replacement(s).

STEP

Equation at the end of step 1

(3x • (y2)) • (0 - (5x2 • y))

STEP

Equation at the end of step

3xy2 • -5x2y

Multiplying exponential expressions :

3.1 x1 multiplied by x2 = x(1 + 2) = x3

Multiplying exponential expressions :

3.2 y2 multiplied by y1 = y(2 + 1) = y3

I believe the answer is ( -3•5x3y3)

Which products result in a difference of squares or a perfect square trinomial? check all that apply. (5x 3)(5x – 3) (7x 4)(7x 4

Scilla [17]

(7x + 4)(7x + 4) and (x – 9)(x – 9) are Perfect square trinomial. (5x + 3)(5x – 3) and (–3x – 6)(–3x + 6) shows the Difference of squares.

<h3>What is a perfect square?</h3>

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

The following are the answers

(5x + 3)(5x – 3) Difference of squares

(7x + 4)(7x + 4) is a Perfect square trinomial

(2x + 1)(x + 2) has Neither a difference of squares nor a perfect square trinomial.

(4x – 6)(x + 8) has Neither a difference of squares nor a perfect square trinomial.

(x – 9)(x – 9) is Perfect square trinomial

(–3x – 6)(–3x + 6) = $(-3x)^2- ( -6)^2$ Difference of squares.

Directed line segment DE has endpoints D(-4,-2) and E(1,8). Point F divides DE such that DF:FE is 3:2What are the coordinates of

VMariaS [17]

The Solution.

The given points are

$D(-4,-2)\text{ and E(1,8)}$

The formula is

$\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}$

In this case,

$m=3,n=2$

Therefore,

$\begin{gathered} (\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}) \\ =(\frac{3(1)+_{}2(-4)_{}}{3+2}_{},\frac{3(8)_{}+2(-2)_{}}{3+2}) \\ \end{gathered}$ $=(\frac{3-8}{5},\frac{24-4}{5})=(-\frac{5}{5},\frac{20}{5})$ $=(-1,4)$

Hence, the correct answer is (-1, 4) (option 3)

eduard

Answer:

The banner is 10 2/3 ft long

Step-by-step explanation:

1 1/3 = 4/3 times the width of the banner:

4/3 * 8 feet wide = 4/3 * 8 = 32/3 = 10 2/3 feet long

The banner is 10 2/3 feet long. :)
