Answer:
x = 4.85 feet
Step-by-step explanation:
Original area of the petting farm = 10 × 14
= 140 square feet
.
New area = double the original area = 140 * 2
= 280 square feet
New area of the petting farm =
Width × length
280 = (10+x) × (14+x)
280 = 140 + 10x + 14x + x²
280 - 140 = x² + 24x
140 = x² + 24x
x² + 24x - 140 = 0
Solve the quadratic equation
x = -b ± √b² - 4ac / 2a
= -24 ± √(24)² - 4*1*-140 / 2*1
= -24 ± √ 576 - (-560) / 2
= -24 ± √ 576 + 560 / 2
= -24 ± √1,136 / 2
= -24 ± 4√71 / 2
= -24/2 ± 4√71/2
= -12 ± 2√71
x = 4.8523 or x = -28.8583
x can not be a negative value
Therefore,
x = 4.85 feet to the nearest hundredth

Answer:
The value of x is 67
Step-by-step explanation:
If two adjacent angles formed a line, then they called a pair of linear anglesThe measure of the pair of linear angles is 180°In the given figure
∵ One side of the triangle is extended to form an exterior angle of 113°
∵ The angle of 113° and the angle of x° are adjacent angles
∵ They formed a line (the side is extended)
→ That means they formed a pair of linear angles
∴ The angle of 113° and the angle of x° formed a pair of linear angles
∵ The measure of the pair of linear angles = 180°
∴ 113° + x° = 180
→ Subtract 113 from both sides
∵ 113 - 113 + x = 180 - 113
∴ x = 67
∴ The value of x is 67

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $30 monthly fee and charges an additional
$0.14 for each minute of calls. The second plan has a $22 monthly fee and charges an additional $0.19 for each minute of calls. For how many minutes of calls
will the costs of the two plans be equal?
Answer:
The plans will be equal at 160 minutes of call
Step-by-step explanation:
1st plan: y = 0.14x + 30
2nd plan: y = 0.19x + 22
0.14x + 30 = 0.19x + 22
Subtract 0.19x from both sides;
-0.05x + 30 = 22
Subtract 30 from both sides;
-0.05x = -8
Divide both sides by -0.05
x = 160

The measure of angle JLM is 140°. The measure of angle JKL is 75.
What is the measure of angle KJL
Enter your answer in the box.
Answer:
KJL is 65 degrees
Step-by-step explanation:
If JLM is 140 deg. JLK is 40 deg the two angles on transverse line must equal 180 total.
JKL being 75 degf, sum that with JLK of 40= 115 deg
180-115= 65 deg Sum of interior angles on a triangle add up to 180 deg.
At least that is how I remember it, you can also graph it and check it out.

Help me pls, for number 19, I have absolutely no idea what I’m supposed to do.
All you have to do is take the value listed above for g(x) and set it equal to 16.
-3x+1=16.
Subtract 1 from both sides
-3x=15
divide both sides by -3
x=-5

Sarah says that 26 ÷ 8 equals 14 ÷ 4 because both are “3 R2.” Show her mistake using decimal division. What is 26 ÷ 8? Give your answer in decimals. 26 ÷ 8 =___. Please helpppppp
Answer: 3.25
Step-by-step explanation:
Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.
26 ÷ 8 in decimal will give us 3.25

A taxi driver can cover a distance of 130.16 miles per gallon per 5 gallons of gas if the same taxi driver travel 60 miles at the same miles per gallon the second day what would be the best estimate of number of gallons a taxi driver use
Answer:
[tex]Gallons = 2.305[/tex]
Step-by-step explanation:
Given
Rate = 130.16 miles for 5 gallons
Required
Number of gallons used for a journey of 60 miles
The rate in miles per gallon is calculated as:
[tex]Rate = \frac{Distance}{Gallons}[/tex]
When distance = 130.16 and gallons = 5, we have:
[tex]Rate = \frac{130.16}{5}[/tex]
[tex]Rate = 26.032[/tex]
When distance = 60 miles.
Substitute 60 for distance and 26.032 for rate in [tex]Rate = \frac{Distance}{Gallons}[/tex]
[tex]26.032 = \frac{60}{Gallons}[/tex]
Cross Multiply
[tex]Gallons * 26.032 = 60[/tex]
[tex]Gallons = \frac{60}{26.032}[/tex]
[tex]Gallons = 2.305[/tex] --- approximated
