Answer:

13. $D = 18$

14. $S = (x, y + 6)$

Step-by-step explanation:

13.

Given

$M = (-8,2)$

$S = (10,2)$

Required

Determine the distance between M and S

Distance (D) is calculated using:

$D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$

Where

$(x_1,y_1) = (-8,2)$

$(x_2,y_2) = (10,2)$

$D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$

$D = \sqrt{(10 - (-8))^2 + (2 - 2)^2}$

$D = \sqrt{(10 +8)^2 + 0^2}$

$D = \sqrt{18^2 + 0}$

$D = \sqrt{18^2}$

$D = 18$

Hence, the distance between M and S is 18 units

14.

The coordinate of S and P are not given,

So, I'll just use (x,y) for P

i.e.

$P=(x,y)$

Required

Determine the coordinates of S

If S is 6 units above P, then the coordinates of S is

$S = (x, y + 6)$

i.e. we add the units to the y coordinate of P.

S_A_V [24]

Answer:

(x+10)(x+10)

or (x+10)²

Step-by-step explanation:

this factories can use this

a² + 2ab + b²

; (a)² + 2(a)(10) + (b)²

= (a+b)²

hope it helps you ☺️

A rectangle has one side that measures 3x + 1 and another that measures 4y + 3. Keith says that the perimeter of the rectangle i

mart [117]

Answer:

he added the dimensions of the rectangle. He used the wrong formula. the formula he used was length + breadth. He should have multiplied by 2

6x + 8y +8

Step-by-step explanation:

Perimeter of a rectangle = 2 x (L + B)

L = length

b = breadth

2 (3x + 4y + 4. ) = 6x + 8y +8

Question is: Solve -7(x+6)=4(x+6)

Alina [70]

$\huge\boxed{x=-6}$

Hey there! Our goal here is to isolate the variable on one side of the equation.

$\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\\-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\\-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\\-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\\-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\\x&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}$
