what is the perimeter of (-2,1) (3,1) (3,-1) (-2,-1)
Answer:
14
Step-by-step explanation:
Given the points (-2,1), (3,1), (3,-1), and (-2,-1) that are the vertices of a quadrilateral, you want to find the perimeter.
PerimeterThe perimeter of a plane figure is the sum of the lengths of its sides. When you plot these points, you see they define a rectangle with horizontal sides of length (3-(-2)) = 5, and vertical sides of length (1 -(-1)) = 2. There are two sides of each of these lengths, so the perimeter is ...
P = 2(L+W) = 2(5 +2) = 2(7)
P = 14
The perimeter of the figure is 14 units.

1. Olivia and Brandon take a road trip that is 1, 792 miles. The odometer reading on their car when they start out is
58, 236 miles. After one day, the odometer reading is 58, 857 miles. How many miles do they have left before they
reach their destination?
1,351 miles
1,171 miles
Answer:
1,171 miles
Step-by-step explanation:
The trip is 1792 miles.
They have driven (58857 - 58236) miles of the trip so far (because the odometer change is equal to the distance driven).
(58857 - 58236) = 621
They still need to drive 1792 - 621 miles
1792 - 621 = 1171
So they have 1171 miles left until they complete the trip.
Jasmine used the number line to find the distance between 0 and 5. what was Jasmine’s error
1.jasmine should have counted from 5 to 0
2.jasmine started with the wrong integer.
3.jasmine gave a negative answer for distance.
4. Jasmine ended with the wrong integer.
The correct answer is option c.
Jasmine gave a negative answer for distance.
The number line is the main visual base in statistics and we often want to look at two points on the number line and determine the distance between them. This is used to find the base of a rectangle or another figure that lies above the number line. By the end of this section, you will be able to determine the distance between any two points on a number line that comes from a statistics application.
The absolute value of 5 is 5, because it is 5 units away from 0. A negative number is a number that is less than zero. On a horizontal number line, negative numbers are usually shown to the left of 0. Two numbers are opposites if they are the same distance from 0 and on different sides of the number line.

The real solution of the equation are +0.77, -0.77, +1.85, -1.85.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
Given:
x^4 − 4x^2 + 2 = 0
(x²)² - 4x² + 2 =0
let us consider y= x², then the above equation become
y² - 4y + 2 =0

The lengths of AB and CD are 12 and 26.5 units
How to find the lengths of AB and CD?The given parameters are
AB = 2x + 3
BC = 21
CD = 7x - 5
AD = 11x + 10
The points are on line AD
So, we have
AD = AB + BC + CD
This gives
11x + 10 = 2x + 3 + 21 + 7x - 5
Evaluate the like terms
2x = 9
Divide by 2
x = 4.5
Substitute x = 4.5 in AB = 2x + 3 and CD = 7x - 5
AB = 2 * 4.5 + 3 = 12
CD = 7 * 4.5 - 5 = 26.5
Hence, the lengths of AB and CD are 12 and 26.5 units

HURRY IM TIMED Explain how to find the estimated sum of 5/8+2/9
Answer:
61/72
Step-by-step explanation:
first find the lowest common denominator - basically in this case the lowest number that goes into 8 and 9 - 8 x 9 which is 72, then
8 goes into 72 9 times so do 9 x the numerator (5)
9 x 5 = 45
Do the same for the second fraction, 9 goes into 72 8 times so do 8 x numerator (2)
8 x 2 = 16
Now add 45+ 16 = 61 ( this is your numerator)
and you keep the denominator (72) the same, so the answer is 61/72

Consideri the expression 5/6(1/2x+6) - 3x
Therefore, the value for the algebraic expression 5 / 6 ( 1 / 2 (x) + 6 ) - 3x for x = 12 is -26.
Given algebraic expression is 5/6(1/2 (x) + 6 )-3x
As we know An algebraic expression in mathematics is an expression that consists of variables and constants, along with algebraic operations such as addition, subtraction, etc., and are made up of terms
Solve the expression for x = 12
To solve this algebraic expression we have to substitute the value of x = 12 in an expression as below
= 5 / 6 ( 1 / 2 (x) + 6 ) - 3x
Substitute the value of x in the given expression as below
= 5 / 6 ( 1 / 2 * 12 + 6 ) - 3 * 12
= 5 / 6 ( 6 + 6 )) - 36
= 5 / 6 ( 12 ) - 36
= 5 * 2 - 36
= 10 - 36
= -26
Therefore, the value for the expression 5 / 6 ( 1 / 2 (x) + 6 ) - 3x for x = 12 is -26.

To conserve water, many communities have developed water restrictions. The water utility charges a fee of $38, plus an additional $1.28 per hundred cubic feet (HCF) of water. The recommended monthly bill for a household is between $57 and $87 dollars per month. If x represents the water usage in HCF in a household, write a compound inequality to represent the scenario and then determine the recommended range of water consumption. (Round your answer to one decimal place.)
the recommended range of water consumption is defined by the compound inequality:
14.84 ≤ x ≤ 38.28
How to write a compound inequality?The water utility charges a fixed amount of $38 plus $1.28 per hundred cubic feet of water. So, if you consume x hundred cubic feet of water, the cost is given by the linear relation:
$38 + $1.28*x
Now, this needs to be between $57 and $87 (values included) so we can write the inequality:
$57 ≤ $38 + $1.28*x ≤ $87
Now we just need to solve this for x. If you subtract $38 in both sides you will get:
$57 - $38 ≤ $1.28*x ≤ $87 - $38
$19 ≤ $1.28*x ≤ $49
Now we divide by $1.28 so we get:
$19/$1.28 ≤ x ≤ $49/$1.28
14.84 ≤ x ≤ 38.28
So to be in the recommended range of water consumption, your water consumption x must be in the range:
