Solution:
perimeter of rectangle = 2 ( Length + Width )
a square has all sides of similar length. thus [ length = width ]Find length/width:
2 (length + length) = 48
2(length) = 24
length = 12 cm
width = 12 cm
⇒ The dimensions of square: 12 x 12
If the square cut into half, the dimensions of either length or width will half.
Therefore, the perimeter of rectangle:
→ 2 (length + width)
→ 2 ( 12 + 6 )
→ 2 ( 18 )
→ 36 cm

The vertices of a rectangle are located at the coordinates (2, 2), (2, 6), (5, 6), and (5,2). Find the length of the sides of the rectangle and its perimeter. help meeeee
Answer:
length of rectangle = 4 units
width of rectangle = 3 units
Perimeter of a rectangle = 14 units
Step-by-step explanation:
Properties of a rectangle:
Opposite sides are parallel and equal in lengthEach interior angle is 90°From inspection, we can see that (2, 2) and (2, 6) have the same x-values. So (2, 6) is above (2, 2) on the same vertical line.
To calculate the distance between them, find the difference between their y-values: 6 - 2 = 4
Therefore, one pair of sides of the rectangle are 4 units in length.
From inspection, we can see that (2, 6) and (5, 6) have the same y-values. So (5, 6) is to the right of (2, 6) on the same horizontal line.
To calculate the distance between them, find the difference between their x-values: 5 - 2 = 3
Therefore, the other pair of sides of the rectangle are 3 units in length.
Therefore:
length of rectangle = 4 unitswidth of rectangle = 3 unitsPerimeter of a rectangle = 2 × length + 2 × width
= 2 × 4 + 2 × 3
= 8 + 6
= 14 units

subtract 7/10 - 1/5 simplify your answer
Answer:
1/2
Step-by-step explanation:
7/10 - 1/5
=> 7/10 - 1*2/5*2
=> 7/10 - 2/10
=> (7-2)/10
=> 5/10
=> 1/2
first, you have to make sure they have the same bottom number so you would make 1/5 2/10.
7/10-2/10
which is 5/10
you would simplify it and get 1/2 because 5 is half of 10

Please help me with this question
Answer:
Using distributive property you jsut multiply the number outside the parenthesis by each number inside.
In this case its
1/2 ( p + 4)
So multiply each number (or variable) by 1/2
And leave the sign if nothing changes
1/2 * p = 1/2p
1/2 * 4 = 2
You’d get
1/2p + 2
And this please, usually I’ll tryy my best to do it without free answers but my teacher hasn’t been on for awhile so we have subs and we don’t do anything but go on Aleks I don’t understand:/
Answer:
Explaining the concept:
We have been given a piecewise function, which means that this function is defined differently for different values
notice that in the function, at the end of each row, we have an 'if' statement
if the input value satisfies the if statement, the function of that respective row will be used
Finding the Values:
h(-5):
since the input value is unequal to -2, the first function will be used (because the if statement at the end of the first function is satisfied by the input value)
h(x) = -(x/4) - (2) (since x ≠ -2)
replacing x with -5
h(-5) = -(-5/4) - 2
h(-5) = (5-8) / 4
h(-5) = -3/4
h(-2):
From the 2 if statements, we notice that this input value satisfies the second statement (x = -2)
Therefore, the second function will be used
h(x) = -1 (for x = -2)
h(-2) = -1
h(0):
This input values satisfies the first if statement.
Hence, the first function will be used
h(x) = (-x/4) - 2 (for x ≠ -2)
replacing x with 0
h(0) = (-0/4) - 2
h(0) = -2

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y is less than negative 3 over 4 times x minus 1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically
9514 1404 393
Answer:
A) The graph is the quadrant of the coordinate plane that lies between the two lines and to the left of the point (-2 14/15, 1 1/5)
B) no; it does not satisfy either inequality
Step-by-step explanation:
A) The boundary line defined by the first inequality is a dashed line with a slope of 3 and a y-intercept of 10. Shading is above the line (and to its left).
The boundary line defined by the second inequality is a dashed line with a slope of -3/4 and a y-intercept of -1. Shading is below the line (and to its left).
The two lines cross at the 2nd-quadrant point (-2 14/15, 1 1/5). The solution area is the area between the crossing lines and to the left of that point. Neither that point nor any point on either line is part of the solution area.
The solution area is the doubly-shaded area in the attached graph.
__
B) The first-quadrant point (8, 10) is not in the solution area, since the solution area is comprised of parts of quadrants 2 and 3 only.
We can see that (8, 10) will not satisfy either inequality:
10 > 3(8) +10 . . . . not true
10 < -3/4(8) -1 . . . . not true

The missing number that will make both expressions to be equivalent expressions is: 110.
What are Equivalent Expressions?Two expressions are equivalent if they have the same value.
Given the following expressions:
Expression I: 200r -(-110)Expression II: _ + 200rLet x represent the missing number in the second expression. Thus, equate both expressions and solve for x.
200r -(-110) = x + 200r
200r + 110 = x + 200r
Add like terms
200r - 200r + 110 = x
110 = x
x = 110
Therefore, the missing number that will make both expressions to be equivalent expressions is: 110.
