Step-by-step explanation:
The area of a triangle is
[tex]A=\frac{1}{2}bh[/tex] and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:
[tex]6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}[/tex]
That's the height that we will sub into the area formula:
[tex]A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8[/tex]

i am glad to help you have a good day:) stay safe.
The value of the perimeter of the square become is 23.6x - 13.2.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
What is the perimeter of the square?The perimeter of a square is defined as the addition of the lengths of the square.
The perimeter of a square = 4a
Where a is the length of the side of the square
The perimeter of a square = 4a
Here a = 5.9x-3.3
Substitute the value of a = 5.9x - 3.3 in the formula, and we get
Perimeter of square = 4(5.9x - 3.3)
Perimeter of square = 23.6x - 13.2
Therefore, the value of the perimeter of the square become 23.6x - 13.2.

1. PY =8
2. XM =42
3. PM = MY
4. MY = 8
Answers
Answer:
PY = 8
Step-by-step explanation:
Since, a point (here P) lying on the perpendicular bisector of a segment is equidistant from the extreme points (here X and Y) of the segment.
So, PX = PY
But, PX = 8 (given)
Therefore, PY = 8
Solve for X ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
Answers
Answer:
(x - 8) + (2x - 4) = 15
3x - 12 = 15
+12 +12
3x = 27
Divide by 3 on both sides:
x = 9
Answer:
x = 9
Step-by-step explanation:
➼first, let's put it into an equation
(x - 8) + (2x - 4) = 15
➼next, add up the common terms
-since there are two variables with x and two number variables, we will rewrite the equation and solve
(-8 - 4) + (2x + x) = 15
-8 - 4 = -12
2x + x = 3x
plug in:
-12 + 3x = 15
➼now get x alone by first getting rid of 12
-do this by doing opposite and adding 12 to everything
-12 + 12 = 0
12 + 15 = 27
plug in:
3x = 27
divide 3 both sides
27/3 = 9
3/3 = 0
➼x = 9

what is the range of this graph?
pls help me and explain
ty <3
Answers
Answer:
[4, ∞)
Step-by-step explanation:
The range of a graph is the values of y for that graph.
We can see that the lowest y value of the graph occurs at the minimum, (0, -4). So the lower limit of the range is -4.
On the right side, the graph continues to reach upward indefinitely. That means that we can say that the upper limit of the range is infinity.
We can write this in different forms. I will write it here in interval notation:
[4, ∞)
The "[" signifies that the value of -4 is included in the range, and the ")" signifies that the range goes up to infinity.
