Answer: 129 Feet
Step-by-step explanation:
You can make an equation where Height=h, and Base=b. So going backwards with the first question, the base will equal 4 times the height: b=4h, and 11 less. b=4h-11. The the other equation will be just that the base plus the height is 49. b+h=49. Then you put that into y=mx+b form. The first equation already is, and the second equation would be b=49-h. So, since the equations equal the same things, you throw away the b. Then you make a new equation by having 4h-11 equal 49-h. Since this is true seeing as they are the same triangle. Then you just use propreties of equality for the equation. You end up with 5h=60. The. You divide 60 by 5 to make 5h just equal h. So you get h=6. Then, like the qeuation said, the base (unknown) plus the height (6) is 49. So to get from 6 to 49, the answer is 43. The formula for that area of a triangle is (base x height) /2 = area. So 43 times 6 is 258. Then divided by 2 is 129. So the area of the triangle is 129.
The area of the triangle is 222 square feet.
Area of a triangle
The formula for calculating the area of the triangle is expressed as:
A = 0.5bh
b is the base of the triangleh is the height of the triangleThe base of a triangle is eleven feet less than four times its height,
b = 4h - 11
Also, if the sum of the lengths of the base and height of the triangle is 49 is expressed as:
b + h = 49
4h-11+h = 49
5h = 49 + 11
5h = 60
h = 12
Since 4h = b + 11
4(12) = b + 11
b = 48 - 11
b = 37
A = 0.5(12)(37)
A = 222ft^2
Hence the area of the triangle is 222 square feet.

A fair die is roll 4 times find the probability of getting 2 six
The probability of getting 2 six when a fair die is rolled 4 times is given as 1/216.
What is the way to find probability?Probability for any event is the ratio of number of favorable events to the total possible events.
It deals with the measurement of the chance and its value is always in the interval [0, 1].
The sample space and the number of favorable outcomes are given as follows,
The total number of ways two 6 can come out of the 4 times = ⁴C₂ = 6
And, the total number of outcomes for the 4 roll of dice = 6⁴
Now, the probability is given as,
P(6 two times) = 6/6⁴ = 1/216

Which transformation causes the image to be larger or smaller than the pre-image?
A dilation is a type of transformation causes the image to be larger or smaller than the pre-image.
What is dilation?A dilation is a type of transformation that changes the size of a figure without changing its shape. Dilations can make a figure larger or smaller.
In a dilation, the original figure is called the preimage. The dilated figure is called the image. Figures are dilated from a fixed point, called the center of dilation.Dilations also scale all sides of a figure by the same factor. As a result, dilations preserve angle measures and the ratio between corresponding parts.When dilating a figure, the different parts of the figure are multiplied by the scale factor.
In a dilation, the scale factor refers to the ratio between the corresponding sides of the preimage and the image. Therefore, the scale factor, k, can be calculated by dividing the length of one part in the image with the corresponding part in the preimage. The length of the preimage part should always be in the denominator as it belongs to the original figure.

If x:(x+3) = 2:3
find x
Answer: -6
Step-by-step explanation:
If x:(x+3) = 2:3, we can set up the following equation:
x / (x+3) = 2/3
Next, we can multiply both sides of the equation by 3 to get rid of the fraction on the right side:
3 * (x / (x+3)) = 3 * (2/3)
This gives us:
x / (x+3) = 2
Finally, we can multiply both sides of the equation by (x+3) to get rid of the fraction on the left side:
x = 2 * (x+3)
We can then solve for x by rearranging the terms on the right side of the equation:
x = 2x + 6
Subtracting 2x from both sides gives us:
x - 2x = 6
This simplifies to:
-x = 6
Finally, we can divide both sides of the equation by -1 to solve for x:
x = -6
Therefore, x = -6.

What are the roots of the quadratic equation 2x² √ 5x 2 0 Using the quadratic formula?
The roots of the quadratic equation 2x² + 5x - 2 = 0 are -2.7 and 1.3.
The quadratic equation is 2x² + 5x - 2 = 0.
We can solve this equation using the Quadratic Formula:

Where a = 2, b = 5, and c = -2.
Substituting these values into the formula, we get:
x = [-5 ± Â√(5² - 4(2)(-2))] / 2(2)
x = [-5 ± Â√41] / 4
x = [-5 ± Â√41] / 4

What is the nature of the roots of the discriminant of the equation 4x² 3x 1 0?
The roots of the discriminant of the equation 4x² + 3x + 1 = 0 are complex and imaginary.
The discriminant of a quadratic equation is a value calculated by subtracting the square of the coefficient of the x term from four times the coefficient of the x² term, and then multiplying it by the constant term. For this equation, the discriminant is calculated as D = b2 - 4ac, where b = 3 and c = 1. This gives us D = 32 - 4(4)(1) = -7. Since the discriminant is negative, this means that the roots of the equation are complex and imaginary.
