What is the value of x after these statements if the starting value of x is 3.

kolbaska11 [484]

[A]
$3^{2}=9$
$5^{3}=125$
$9\neq25$

Ignore

[B]
$3^{2} = 9$
$9 \ \textgreater \ 3$
Yes

$3^{3}=27$
$4( 3^{2})=36

27 \ \textless \ 36$
Yes

Therefore
$x=3+2=5$

[C]
$4^{5}=1024

 5^{4}=625

1024\ \textless \ 625$
No

$5^{5}=3125

 5^{5}=3125

3125\ \textgreater \ 3125$
No

Ignore

[D]
$5^{5}=3125

 2^{5}=32

3125\ \textgreater \ 32$
Yes

$5^{2}=25
25\ \textless \ 11$
No

Therefore
$x=5+8=13$

[E]
$8\ \textgreater \ 7$
Yes

Therefore
$x = 13^{2}=169$

Write two equivalent expressions to represent the area of the rectangle below.

Goshia [24]

Answer:

$A=(n-3)2\ units^2$

$A=(2n-6)\ units^2$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

$L=(n-3)\ units\\W=2\ units$

substitute

$A=(n-3)2\ units^2$

Apply distributive property

$A=2(n)-2(3)$

$A=(2n-6)\ units^2$

What is the circumternence

AfilCa [17]

Circumference of a circle is the distance around the circle. This can be found by using the equation below

2*pi*radius

Our diameter, as shown, is 9cm. Since radius is half of the diameter, our radius is 4.5cm.

Therefore, our circumference is...

2 * pi * 4.5 = 9pi cm total

The length of a parking Lot is 5 yards more than the width. If the area of the parking lot is 66 square yards, find the dimensio

Brums [2.3K]

Answer:

6 yards by 11 yards

Step-by-step explanation:

Factors of 66 are ...

66 = 1·66 = 2·33 = 3·22 = 6·11

The last pair of factors differ by 5, so represent the solution to the problem.

The width of the parking lot is 6 yards; the length is 11 yards.
