Answer:
1225 cm²
Step-by-step explanation:
Keliling persegi diberikan sebagai 4 × a
Dimana a = Panjang sisi
Keliling persegi di atas = 140
Karenanya:
4a = 140
a = 140/4
a = 35 cm
Panjang sisi bujur sangkar = 35cm
Luas persegi = (Panjang sisi) ²
Karenanya:
Luas persegi = (35cm) ²
= 1225 cm²
Luas persegi sebelum membagi adalah 1225 cm²

Plot the vertex and the axis of symmetry of this function on the provided graph.
f(x) = (x + 2)^2 − 6
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2

A rectangular swimming
pool has a perimeter of
150 meters. The length of
the pool is twice the width
of the pool. What is the
length of the pool?
Answer:
77
Step-by-step explanation:
perimeter=150
lets name the length x
length=x
width=x-2
2[x±x-2]=150
2x±2x-4=150
4x=154
154÷4=77
x=77
The length of the pool is 50 meters and this can be determined by using the formula of the perimeter.
Given :
A rectangular swimming pool has a perimeter of 150 meters. The length of the pool is twice the width of the pool.The following steps can be used in order to determine the length of the pool:
Step 1 - The formula of the perimeter of the rectangle is given by:
P = 2(l + w)
where l is the length of the rectangle and w is the width of the rectangle.
Step 2 - According to the given data, the length of the pool is twice the width of the pool that is:
l = 2w --- (1)
Step 3 - Now, substitute the known terms in the formula of the perimeter.
150 = 2(3w)
150 = 6w
w = 25 meters
Step 4 - Now, substitute the value of w in the equation (1).
l = 2(25)
l = 50 meters.

The longest side of triangle is 10 cm which group of line segments could form the other 2 sides of the triangle
Answer
A 5cm and 5 cm
B 7cm and 8cm
C 4cm and 4cm
D 9cm and 10 cm
Please i need to know
Answer:
The group of line segments that could form the other 2 sides of the triangle is;
B. 7 cm and 8 cm
Step-by-step explanation:
The triangle inequality theorem states that the sum of the length of any two sides of a triangle is larger than the length of the third side
The given parameter of the triangle is that the length of the longest side of the triangle = 10 cm
Let, 'a', and 'b', represent the remaining two sides of the triangle
Therefore, by the triangle inequality theorem, we have;
(1) a + b > 10 cm
(2) 10 cm + a > b
(3) 10 cm + b > a
The option that satisfies condition (1), (2), and (3) are options 'B' and 'D', for which we have;
7 cm + 8 cm = 15 cm > 10 cm
10 cm + 7 cm = 17 cm > 8 cm
10 cm + 8 cm = 18 cm > 7 cm
9 cm + 10 cm = 19 cm > 10 cm
10 cm + 9 cm = 19 cm > 10 cm
10 cm + 10 cm = 20 cm > 9 cm
Therefore, the possible combination of the other two sides are;
7 cm and 8 cm or 9 cm and 10 cm
However, a side of option 'D' is 10 cm and given that the longest side of the triangle = 10 cm, the length of each of the other two side should be less than 10 cm and the only given possible combination of the other two side should be option 'B', 7 cm and 8 cm.
Answer:
B 7cm and 8cm

find the volume of metal required to make a closed box of thickness 1 cm with external measurements 12 cm × 7 cm × 10
Answer:
The volume of the metal is:
[tex]V_{t}=548\: cm^{3}[/tex]
Step-by-step explanation:
First, let's find the volume of the front face of the square:
[tex]V_{1}=12*7*1=84\: cm^{3}[/tex]
The back face is the same, so we have:
[tex]V_{2}=84\: cm^{3}[/tex]
The volume of the side faces will be:
[tex]V_{3}=7*10*1=70\: cm^{3}[/tex]
[tex]V_{4}=70\: cm^{3}[/tex]
And finally, the volume of the top and bottom side faces of the box will be:
[tex]V_{5}=12*10*1=120\: cm^{3}[/tex]
[tex]V_{6}=120\: cm^{3}[/tex]
The total volume of the metal will be:
[tex]V_{t}=V_{1}+V_{2}+V_{3}+V_{4}+V_{5}+V_{6}[/tex]
[tex]V_{t}=2(84)+2(70)+2(120)[/tex]
[tex]V_{t}=548\: cm^{3}[/tex]

Consider this system of equations, which equation represents the first equation written in slope-intercept form? 5x - 2y = 10 O y=x-5 oy-x+10 o y--x+10 O y=-5x -5 ..... brainlyist for who is right
Answer:
The answer is A
Step-by-step explanation:
this isnt my answer it is someone named baylee in the comments, i tried it and it was right .
As per the given data, the slope-intercept form of the first equation is y = x - 5, which is represented by option A.
What is slope-intercept?The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept.
The equation that represents the first equation written in slope-intercept form is:
y = x - 5
To convert the equation 5x - 2y = 10 into slope-intercept form, we need to isolate y on one side of the equation.
Starting with 5x - 2y = 10:
Subtract 5x from both sides: -2y = -5x + 10
Divide both sides by -2: y = (5/2)x - 5
Now, we can simplify the expression (5/2)x - 5 to the form y = mx + b, where m is the slope and b is the y-intercept.
Therefore, the correct option is A.

To rent a bounce house: At Mike's Bounce Shop costs $30 plus $2 per hour. At Jose's Bounce Rentals, it costs $12 plus $8 per hour. After how many hours will the rental cost at both shops be equal? What do your variables represent?Solve the problem using the Equal Values Method. Show your work for finding x AND y.
Answer: After 3 hours both will have the same cost.
Step-by-step explanation:
Let x = Number of hours and y be the total cost.
Total cost = Initial cost + (cost per hour)(Number of hours)
At Mike's Bounce Shop,
Total cost (y)= 30+2x
At Jose's Bounce Rentals,
Total cost(y) = 12+8x
When both shops have the same cost, then
[tex]12+8x=30+2x\\\\\Rightarrow\ 8x-2x=30-12\\\\\Rightarrow\ 6x=18\\\\\Rightarrow\ x=3[/tex]
Total cost = 12+8(3)=12+24=$36
Hence, After 3 hours both will have the same cost.
