The diagonals of square ABCD intersect at point E. If BE = 2x + 1, and AC = 3(6x-4), find BD.
Answer:
X=1
BD=AC=3(6x-4)=3(6(1)-4)=6
BD=6
Square is a polygon with 4 equal sides. The value of line BD is 6 units.
What is a square?A square is a polygon with 4 sides, such that all the four sides of the polynomial are equal, also all the angles of the square are of 90°.
As it is given that the diagonals of square ABCD intersect at point E. And, we know that the diagonals of the square bisect each other. therefore, we can write,
BD = 2BE
Substituting the values, we will get,
[tex]3(6x-4) = 2 \times(2x+1)\\\\18x-12 = 4x+2\\\\18x-4x = 2+12\\\\14x = 14\\\\x = \dfrac{14}{14}\\\\x = 1[/tex]
Thus, the value of x is 1.
We know that the diagonal of a square are equal, therefore, the value of the diagonal BD can be written as,
[tex]BD = AC = 3(6x-4)[/tex]
Substitute the value of x as 1, therefore, the value of BD can be written as,
[tex]BD = 3[6(1)-4]\\\\BD = 3(6-4)\\\\BD = 3 \times 2\\\\BD = 6[/tex]
Hence, the value of line BD is 6 units.

Paul will roll two standard dice simultaneously. If Event A = both dice are odd and Event B = at least one die is even, which of the following best describes events A and B?
Answer:
Mutually Exclusive
Dependent
Step-by-step explanation:
Given that both events cannot occur at the same time, that is "both dice cannot be odd (event A) if at least one of the dice is even (event B).
Hence, this is MUTUALLY EXCLUSIVE.
Also, given the fact that the occurrence of one event (event A) affects the probability of the other (event B).
Hence, this is DEPENDENT.

[tex]40\frac{5}{8}mm^2[/tex]
Step-by-step explanation:
To find the area of a triangle, one must use the formula,
[tex]\frac{base*height}{2}[/tex]
It is given that
- base = [tex]9\frac{3}{4}[/tex]
-height = [tex]8\frac{1}{3}[/tex]
Substitute in the values and solve;
[tex]\frac{9\frac{3}{4}*8\frac{1}{3}}{2}[/tex]
In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;
- base = [tex]9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}[/tex]
- height = [tex]8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}[/tex]
Substitute,
[tex]\frac{\frac{39}{4}*\frac{25}{3}}{2}[/tex]
Cross simplify,
[tex]\frac{\frac{325}{4}}{2}[/tex]
Further simplify,
[tex]\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}[/tex]
Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,
[tex]40\frac{5}{8}[/tex]

Points B,C and D lie on a straight line. AC is perpendicular to BD. BC=6cm and BD=22cm. Triangle ABC has area 42cm^2. Calculate the size of angle x
Answer:
41.18
Step-by-step explanation:
CD=22-6=16
42=1/2×6×AC
AC=14
tanθ=O/A
tanθ=(14/16)
x=tan-1(14/16)
x=41.18
The measure of the angle x in the right triangle ABD is 41.2 degrees.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. Therefore, the sides of the triangle can be found using trigonometric ratios.
area of a triangle = 1 / 2 bh
where
b = base of triangleh = height of triangleHence,
area of a triangle = 1 / 2 × 6 × h
42 = 3h
h = 42 / 3
h = 14 cm
DC = 22 - 6 = 16 cm
AC = 14 cm
tan x = opposite / adjacent
tan x = 14 / 16
x = tan ⁻¹ 0.875
x = 41.1859251657
x = 41.2 degrees.
