so umm this is the answer

Perimeter = 2(length + width)

P = 2(L+w)

We are told the length is 3 times the width...

L = 3w

64 = 2(3w + w)

64 = 2(4w)

64 = 8w

8 = w

L = 3w = 3(8) = 24 cm

Length is 24 cm

width is 8 cm

Answer: distributive property

Step-by-step explanation:

$5(18)=2(18)+3(18)$

$18(2+3) = 2* 18+ 3*18$

$18*5 = 2* 18+ 3*18$

Include parentheses in your answer.<br> (x3 + y3) ÷ (x - y)

-Dominant- [34]

I'm assuming you mean $\frac{x^3+y^3}{x-y}$

we can factor that sum of perfect cubes from $x^2+y^3$ into $(x+y)(x^2-xy+y^2)$

so therefor $\frac{x^3+y^3}{x-y}=\frac{(x+y)(x^2-xy+y^2)}{x-y}$
that is simpliest form

What is the standard form of y= 1/4x +6

viktelen [127]

Answer:

$x-4y=-24$

Step-by-step explanation:

Standard form is Ax + By = C, so we want x to be on the left side

To accomplish this, subtract 1/4x from both sides.

$-\frac{1}{4} x+y=6$

Multiply by -4 to get x to be equal to 1.

$x -4y=-24$

Please help me solve for x =

Sladkaya [172]

Answer:

x = 13

Step-by-step explanation:

Given that Δ NML and Δ PST are similar right triangles, we can set up the following proportional statement to establish their relationship:

$\frac{ML}{NM} = \frac{ST}{PS}$

$\frac{8}{10} = \frac{x - 1}{x + 2}$

Cross multiply:

8(x + 2) = 10 (x - 1)

8x + 16 = 10x - 10

Subtract 8x from both sides:

8x - 8x + 16 = 10x - 8x - 10

16 = 2x - 10

Add 10 to both sides:

16 + 10 = 2x - 10 + 10

26 = 2x

Divide both sides by 2:

$\frac{26}{2} = \frac{2x}{2}$

13 = x

Verify whether x = 13 is the correct value:

$\frac{ML}{NM} = \frac{ST}{PS}$

$\frac{8}{10} = \frac{x - 1}{x + 2}$

$\frac{8/2}{10/2} = \frac{4}{5}$

$\frac{x -1}{x+2} = \frac{13 - 1}{13 + 2} = \frac{12}{15} = \frac{12 / 3}{15 /3} = \frac{4}{5}$

This shows the proportional relationship between $\frac{ML}{NM} = \frac{ST}{PS}$ , and that ΔNML and ΔPST are indeed similar right triangles.

Therefore, the correct answer is x = 13.
