Help I really need the answer to this.
It’s either b or c
It either of those.
Answer:
3
Step-by-step explanation:
The sides are congruent so you can write the equation (4x+9)=21.
Now you subtract 9 from 21 and you get 4x=12.
All you gotta do now is divide and you get x=3.
Hope this helps!:)

Can you map shape I onto shape II by a sequence of transformations? If so, give a sequence of transformations that maps shape I onto shape II.
Yes, the shape I can onto shape II by a sequence of transformations.
Two images are given we have to determine that whether any of shape can onto other shapes.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The shape I can be mapped into shape II through a series of transformations.
The first sequence would involve translating shape I 8 units up and 4 units left, reflecting shape I across the x-axis, then rotating shape I 90 degrees counterclockwise about the origin.
Therefore, the shape I can onto shape II by a sequence of transformations.

A car travels a distance of 145 miles in a time of 2.4 hours.
What is its average speed rounded to 1dp?
Answer:
60.4miles/hr
Step-by-step explanation:
Given parameters:
Distance covered by the car = 145miles
Time taken = 2.4hrs
Unknown:
Average speed of the car = ?
Solution:
Average speed is the rate of change of distance with time;
Average speed = [tex]\frac{distance}{time}[/tex]
Input the parameters and solve;
Average speed = [tex]\frac{145}{2.4}[/tex] = 60.4miles/hr

Below is a diagram of Hillcrest High School. The english and math buildings are congruent rectangles. The art building is a square. The total perimeter of Hillcrest High school’s building is 1,718 feet. Find the value of x. Find the missing perimeters for the buildings.
1. Find the value of x.
2. Find the missing perimeters for the buildings.
3. What is the area of the English building? (plug in your x value!)
Answer/Step-by-step explanation:
1. Perimeter of the building = sum of all the length of the outer borders surrounding the building = 1,718 ft
Thus:
4x - 6 + 2x + 3x + 2(3x + 4) + 3x + 2x + x + x + x + 2x + 4x - 6 + 2(3x + 4) + 4x - 6 + 3x = 1,718
Open the Parentheses
4x - 6 + 2x + 3x + 6x + 8 + 3x + 2x + x + x + x + 2x + 4x - 6 + 6x + 8 + 4x - 6 + 3x = 1,718
Combine like terms
42x - 2 = 1,718
42x = 1,718 + 2
42x = 1,720
x ≈ 41
2. Missing perimeter of Building = 2x + 2x + 4x - 6
Simplify
= 8x - 6
Plug in the value of x
= 8(41) - 6
= 322 ft
3. Area of English Building = length * width
= (4x - 6 + 2x)(3x)
Simplify
= (6x - 6)(3x)
Plug in the value of x
= (6(41) - 6)(3(41))
= (246 - 6)(123)
= (240)(123)
= 29,520 ft²

How many of each coin does he have?
Enter your answers in the boxes.
dimes and
quarters
Answer:
dimes: 50
quarters: 8
Step-by-step explanation:
7 quarters is $1.75 + 1 quarter to make it even and it equals $2.00 then, 10 dimes for each dollar and that would be 50 dimes for $5.00. $2.00 + $5.00 is equal to $7

Suppose you have a line segment with endpoint (-1,2) and midpoint (3,4). Which of the following is the other endpoint of your segment?
Step-by-step explanation:
we know that midpoint of a segment is found from formula
x=(x1+x2)/2
and y=(y1+y2)/2
in this case x=3 and y=4 x2=-1 and y2=2
so x1=2x-x2 =2*3-(-1)=6+1=7
y1=2y-y2=2*4-2=8-2=6
the other endpoint is (7,6)

What is the length of TH, when T (6, 9) and H (-4, -1)?
Answer:
d = 10 sqrt(2)
Step-by-step explanation:
The distance formula is
d = sqrt( (y2-y1) ^2 + ( x2-x1)^2)
d = sqrt( (-1-9) ^2 + ( -4-6)^2)
d = sqrt( (-10) ^2 + ( -10)^2)
d = sqrt( 100+100)
d = sqrt(200)
d = sqrt( 200*2)
d = sqrt(100) sqrt(2)
d = 10 sqrt(2)

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Answer:
The area of the triangle DEF is 10.
Step-by-step explanation:
Area of a Triangle:
A triangle of base B and height H (both must be perpendicular) has an area of:
[tex]\displaystyle A=\frac{BH}{2}[/tex]
The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.
This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:
B=3-(-2)=3+2=5
Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.
H=2-(-2)=4
With these two values, we calculate the area:
[tex]\displaystyle A=\frac{5*4}{2}=10[/tex]
The area of the triangle DEF is 10.

In the diagram, the measure of 1 is 55°. If line y is rotated 5° clockwise about the point of
intersection, what is the new measure of 3?
A. 60°
B. 130°
C. 120°
D. 50°
PLEASE LOOK AT THE PICTURE!!
Answer:
Option (1)
Step-by-step explanation:
Lines X and Y are intersecting at a point.
Two pairs of vertical angles have been formed at the point of intersection.
1). ∠1 and ∠3
2). ∠2 and ∠4
It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]
If line Y is rotated 5° clockwise about the point of intersection of both the lines,
∠1 and ∠3 both will increase by 5°.
Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).
Option (1) will be the answer.
The new measure of angle 3 is 60 degrees
When a point or line is rotated, it must be rotated about a point of rotation
The angle measure is given as:
[tex]\angle 1 = 55^o[/tex]
By vertical angle theorem, we have:
[tex]\angle 3 = \angle 1[/tex]
So, the angle measure becomes
[tex]\angle 3 = 55^o[/tex]
The angle of rotation is given as: 5 degrees.
So, the new measure of angle 3 is:
[tex]\angle 3 = 55^o + 5^o[/tex]
[tex]\angle 3 = 60^o[/tex]
Hence, the new measure of angle 3 is 60 degrees
