Step-by-step explanation:

Let the area of rectangle with given points are as follows :

A(-3,3)

B(3,2)

C(4,-1) = C( x1,y1)

D(-2,-3) = D( x2, y2)

Now,

The distance of CD = root under

(x2-x)^2 +( y2 - y1)^2

= root under (-2-4)^2 + ( -3+1)^2

= root under (-6)^2 + (-2)^2

= root under 36 + 4

= root under 40

= 2root 10

Therefore; the unit number if CD is 2 root 10.

Find all zeros of x^4+x

Yuri [45]

Answer:

-1 and 0

Step-by-step explanation:

X ^4+x = 0;

x*(x^3+1)=0;

x*[(x^3-x)+(x+1)]=0;

x*[x(x-1)(x+1)+(x+1)]=0;

x*(x+1)(x^2-x+1)=0;

Since x^2-x+1=0 has no intersection with the X-axis, there is no x value such that y=0

x=0 or -1

Please Help ASAP. Thanks.

Answer:

a = 2

Step-by-step explanation:

If M is the midpoint, 1/2 of FG = FM since FG is the whole length.

FG = 14a + 1

1/2 FG = 1/2(14a + 1)

1/2 FG = 7a + 1/2

The length of the segment FM = 14.5 and that is the same length as 1/2 FG

7a + 1/2 = 14.5

1/2 = 0.5

7a + 0.5 = 14.5 Subtract 0.5 from both sides

7a = 14.5 - 0.5

7a = 14 Divide by 7

a = 14/7

a = 2

The street sign shown is a regular hexagon with side lengths (4x+30) centimeters. The perimeter of the sign is 798 centimeters.

MrRissso [65]

Answer:

25.75

Step-by-step explanation:

A hexagon has 6 sides so

6(4x + 30) = 798

distribute

24x +180 = 798

take away 180 from both sides

24x = 618

divide 24 both sides to get the variable by itself

X = 25.75

A full glass of water can hold 1/6 of a bottle.

uysha [10]

Answer:

21 glasses of water.

Step-by-step explanation:

You can do a proportion.

$\fraction{1 glass}{1/6 of a bottle)$ or

1 glass/1/6 of a bottle.

x glasses/3.5 bottles.

You can cross multiply.

1/6 times x is 1/6x

1 times 3.5 is 3.5/

1/6x=3.5.

do the reciprocal of 1/6 which is 6.

So, 6 times 3.5 is 21.

Therefore, you have 21 glasses of water.

Why is the percent not the same as the percent you find from he percent of money

nexus9112 [7]

Percentage is a way to express a relation between two numbers as a fraction of 100. In other words, the percentage tells us how one number relates to another. If we know that number A is 25% of number B, we know that A to B is like 25 is to 100 (one more transformation: A is four times smaller than B). This is Percentage Calculator's lesson on what is percentage.
But in money a percent is how many cents past the dollar the number is.
