Answer:

Step-by-step explanation:

Let the side of the square (s) = 3x

Then a rectangle is 3x long and x wide

P = 2l + 2w

40 = 2×3x + 2x = 6x +2x = 8x

x = 40/8 = 5

For the square,

s = 3x = 3 × 5 = 15

P = 4s = 4 × 15 = 60

The perimeter of the square is 60.

Solve <br>In 2x + In 2=0

irakobra [83]

Solving $ln(2x)+ln(2)=0$ we get, $x=\frac{1}{4}$

Step-by-step explanation:

We need to solve: $ln(2x)+ln(2)=0$

Solving:

$ln(2x)+ln(2)=0$

Adding -ln(2) on both sides:

$ln(2x)+ln(2)-ln(2)=0-ln(2)$

$ln(2x)=-ln(2)$

Using logarithmic rule: if $log_a b =c\,\,then\,\, b=a^c$

So,

$2x=e^{-ln(2)}$

Simplifying:

$2x=(e^{ln(2)})^{-1}\\e^{ln(2)}=2\\2x=(2)^{-1}\\2x=\frac{1}{2} \\x=\frac{1}{2x2}\\x=\frac{1}{4}$

So, Solving $ln(2x)+ln(2)=0$ we get, $x=\frac{1}{4}$

Joseph had 7 1/4 ounces of candy to share with his friends. He gave them 2 4/5 ounces of candy when they came over to play video

OleMash [197]

7 1/4 - 2 4/5
Turn the denominator into a common denominator for both fractions:
7 5/20 - 2 16/20
To subtract easier, turn the fractions into an improper fraction:
145/20 - 56/20
Subtract the numerators:
145 - 56 = 89 ---> 89/20
Simplify (to get an answer of):
4 9/20
Add labels:
Joseph has 4 9/20 ounces of candy left

E D 1389 xo С 76.2° B А Find the value of x. O 38.1 O 30.9 69 O 61.8

DanielleElmas [232]

Based on the intersecting secants theorem, the value of x is: B. 30.9°

<h3>What is the Intersecting Secants Theorem?</h3>

The intersecting secants theorem states that when two secants intersect, the measure of the angle they form is half the difference of the intercepted arcs.

Thus, based on the intersecting secants theorem, we would have the following:

x = 1/2(138 - 76.2)

x = 1/2(61.8)

x = 30.9°
