Can someone help me with this problem

Alex_Xolod [135]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

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

A(-3, 0) , B(3, 2)

$AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}$

A(-3, 0), D(-2, -3)

$AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}$

AB = CD and AD = BC

The area of a rectangle:

$A=(AB)(AD)$

Substitute:

$A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20$

The perimeter of a rectangle:

$P=2(AB+AD)$

Substitute:

$P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}$

I'm trying to rearange this equation so that t is the subject and i need help

gregori [183]

Work backwards.

s=ut+(at^2)/2

Subtract ut.

s-ut=(at^2)/2

Multiply by 2.

2(s-ut)=at^2

Divide by a.

2(s-ut)/a=t^2

Find the square root:

$\sqrt{2(s-ut)/a}=t$

What are the solutions to the system of equations <br> {-x+y=4<br> {y+12=x^2+x

Gnoma [55]

Answer:

Step-by-step explanation:

$y=4+x$ ............................................ (1)

$y=x^2+x-12$ ............................................ (2)

now equate both (1) and (2)

$4+x=x^2+x-12$

$=>x^2=16$

$x=-4,4$

now substitute the values of x ,

when $x=-4$ , y becomes 0

when $x=4$ , y becomes 8

so, solution set:

$(-4,0)$ and $(4,8)$

The product of 7 and a number, x, increased by 1 is between 15 and 43. What is the compound inequality that represents the situa

k0ka [10]

Let's assume that number as x

The product of 7 and a number =7x

and then increased by 1

so, it will become

=7x+1

now, it is between 15 and 43

so, we can write as

$15$

now, we can solve for x

Since, we have to isolate x

step-1:

Subtract all the sides by 1

$15-1$

$14$

step-2:

Divide all the sides by 7

$\frac{14}{7}$

$2$

so, solution is

$2$ .............Answer
